Remove non-common flash driver in
board/freescale/m54455evb/flash.c. The non-cfi flash will
use CONFIG_FLASH_CFI_LEGACY to configure the flash
attribute.

Since page size field is changed from oobblock to writesize. But OneNAND is not updated.
- fix bufferram management at erase operation
This patch includes the NAND/OneNAND state filed too.

onenand_print_device_info():
- Now returns a string to be placed in mtd->name,
rather than calling printf.
- Remove verbose parameter as it becomes useless.

Supporting page-aligned reads doesn't incure any sinificant overhead, just
a small change in the algorithm. Also replace in_8 with readb, since there
is no in_8 on ARM.

Also, remove the ctrl variable in favor of passing the constants
directly, and remove redundant (u8) casts.

Note that with older board revisions, NAND boot may only work after a
power-on reset, and not after a warm reset. I don't have a newer board
to test on; if you have a board with a 33MHz crystal, please let me know
if it works after a warm reset.

Environment can be smaller than NAND block size, do not need to read a whole
block and minimum for writing is one page. Also remove an unused variable.

Rather than scanning on boot, scan upon the first attempt to check the
badness of a block. This speeds up boot when not using NAND, and reduces
the likelihood of needing to reflash via JTAG if NAND becomes
nonfunctional.

Use of the non-skipping versions was almost always (if not always)
an error, and no valid use case has been identified.

The hardware has separate registers for block and page-within-block,
but the division between the two has no apparent relation to the
actual erase block size of the NAND chip.

Using current driver elbc sometimes hangs during nand write. Reading back
last byte helps though (thanks to Scott Wood for the idea).
