The RCSR default value for single frame mode is off (a RB contains more than
one frames). But the driver assumes single frame mode apparently. This patch
enables single frame mode for the hardware. It also adds a BUG_ON to make sure
the allocated skb satisfies the hardware alignment requirement and removes
a useless check.

This moves byte count tables to tx domain removing completely
ambivalent shared data. Changes handling of allocation
byte count tables and keep warm consistent memory
Moves general tx scheduler definitions from iwl-4956-hw.h

This patch moves rx status/read registers into
iwl_rx_queue structures. This solution is more memory
hungry but is more structured and provides needed RX/TX
separation

This patch drops unreadable usage of IWL_SET/GET_BITS16 in byte count
tables handling
This patch also cleans a bit the byte count table code and adds
WARN_ON traps on invalid values
This patch is pure cleanup, no functional changes.

The patch adds HW bug W/A FH_RCSR_CHNL0_RX_IGNORE_RXF_EMPTY so that we
can enable again interrupt coalescing. It also uses named constants for
open code.
