As more Davinci 8xx board can be added, move common code
to be shared between boards.
* rebased ontop of Sugosh's patches
* moving the HAWKBOARD_KICK{0,1}_UNLOCK defines to
arch/arm/include/asm/arch-davinci/davinci_misc.h from to
arch/arm/include/asm/arch-davinci/da8xx_common.h
* don't define dram functions in PRELOADER
* move sync_env_enetaddr into existing EMAC ifdef
* use misc.c in hawkboard nand_spl

The patch adds basic board support for TI's OMAP-L138 based
Hawkboard. This board is pretty similar to the da850 EVM. Support for
nand and network access is added in this version.
The following bootup procedure is used.
At reset, the Rom Boot Loader(RBL), initialises the ddr and the nand
controllers and copies the second stage bootloader(nand_spl) to
RAM. The secondary bootloader then copies u-boot from a predefined
location in the nand flash to the RAM, and passes control to the
u-boot image.
Three config options are supported
* hawkboard_config - Used to create the u-boot.bin. Tftp the
u-boot.bin image to the RAM from u-boot, and flash to the nand flash
at address 0xe0000.
* hawkboard_nand_config - Used to generate the secondary
bootloader(nand_spl) image. This creates an elf file u-boot-spl
under nand_spl/. Create an AIS signed image using this file, and
flash it to the nand flash at address 0x20000. The ais file should
fit in one block.
* hawkboard_uart_config - This is same as the first image, but with
the TEXT_BASE as expected by the RBL(0xc1080000). Create the AIS

When this define was introduced, the idea was to provide a soft
migration path for ARM boards to get adapted to the new relocation
support. However, other recent changes led to a different
implementation (ELF relocation), where this no longer works. By now
CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it
actually hurts because it obfuscates the actual code by sprinkling it
with lots of dead and non-working debris.
So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC.

This patch proposes to migrate the davinci_emac driver to using the
eth_device->write_hwaddr function pointer as suggested by Ben Warren.
All the davinci boards had the behaviour, prior to this patch, of
sync'ing the environment variable enetaddr with the MAC address read
from non-volatile storage on boot -- when the two locations disagreed,
the environment variable value took precendence. This patch keeps the
same behaviour but lets eth_initialize take care of it.
This patch refactors davinci_emac setup in the boards so that the MAC
address is read from non-volatile storage into the environment variable
and then the environment variable value is use in eth_intialize. The
only exception is the direct call to davinci_eth_set_mac_addr made by
the da830evm board init which was changed into an assignment of the
enetaddr field.

Split the existing dram_init for da8xx when ARM reloc is enabled, like the
changes to arch/arm/cpu/arm926ejs/orion5x/dram.c in
0f234d263b17ccf1b8fd776eb8c15b7cdb27a887 by Heiko Schocher <hs@denx.de>.
Without these changes gd->ram_size is '0' which leads to incorrect relocation
when CONFIG_SYS_ARM_WITHOUT_RELOC is defined and the board does not boot.
We use get_ram_size to dynamically calculate the available RAM because it runs
on different board version with different ram, as suggested by Heiko in private
communication.
Tested on a da850evm with 128M of DDR2 installed; with both
CONFIG_SYS_ARM_WITHOUT_RELOC defined and undefined.

Davinci: Table driven pinmux configuration
Add code to allow pinmux_config tables to be grouped and configured
as a single resource. This removes multiple calls to the pinmux
configuration code from board_init and allows pinmuxes to be
individually configured and added by data manipulation only.
All related #ifdefs can the be removed from board_init code and
since the compiler optimises away statics, #ifdefs can be reduced in
the data definitions as well.

Move the clock-rate dumping code into the cpu/.../davinci area
where it should have been, enabled by CONFIG_DISPLAY_CPUINFO,
updating the format and showing the DSP clock (where relevant).
Switch boards to use the cpuinfo() hook for this stuff.
Remove a few now-obsolete PLL #defines.

Chips without the EMAC controller won't need the utilities
it uses to read an Ethernet address from EEPROM; so don't
include them needlessly.
Use is_valid_ether() to validate the address from EEPROM.
All-zero addresses aren't the only invalid addresses.
A fully erased EEPROM returns all-ones, also invalid...
Switch those Ethernet utilities to use "%pM" for printing
MAC addresses; and not say ROM when they mean EEPROM.
