Move RX BMC configuration from the radio initialization to the
receive functions to avoid double configuration on TX.

This reverts commit 3253b4dd51.
Accidentally committed, code is not ready yet and only works
occasionaly.

Trigger handover based on indicated slot errors as per ETSI EN 300 175-3
section 11.4.5. Sliding collision indications based on the Q1/Q2 bits is
currently ignores since there appears to be a bug in the sc1442x firmware
in transmitting the Z-field. Additionally bearer-reattempt rate-limiting
is currently missing.

Occasionally after an error the card will deliver spurious interrupts when
reloading the driver. Clear all pending interrupts to avoid this.

Ciphering and synchronization options are similar to the primary
transceiver (the sync bearer is handled seperately), only the
entry points of primary and secondaries differ.

- rename Receive and Transmit functions to RX_ and TX_
- add P00 receive function. This is necessary for channel measurement,
which should measure only over the real packet length.

There's no need to reinitialize the radio configuration when changing
channel modes, just initialize it once in sc1442x_init_slot().

The first byte of the transmitted preamble is currently zero. For some
reason the firmware transmits 5 bytes of firmware, my assumption is that
the first byte is used during ramp-up of the radio.
According to ETS 175 300-02 Chapter 4.9, the ramp-up pattern must be
either the natural extension of the preamble pattern, or the value 0.
Both appear to work equally good, which seems to confirm my assumption.

Accept non-P00 packets with A-field CRC errors and filter them in
software. I_N minimum delay bearers may still accept the B-field.

Use 16 bit writes when copying larger amounts of data. This improves
both read and write speed by roughly 30% in case of the PCMCIA device.

Use P_SC on reception in PP mode to keep the clock synchronized to the FP.
This reduces the phase offset between two coa devices from 15kHz to < 0.5kHz.

Apparently the Type II cards don't work properly unless the Codec is
disabled - scanning, channel hopping etc. is performed, but no FPs
are found at all.

Access to the chip memory needs to be serialized to avoid races between
switch to a bank and actually using it.

Rename all files, constants and functions to reflect the fact that the
driver handles the 14424 as well.
