This patch imports all shared header changes
from carl9170fw.git.
* add some strategic __aligned(4).
This allows the compiler generate optimized code for
architectures which can't access (unaligned/packed)
data efficiently.
("ath9k_hw: optimize all descriptor access functions")
* add a forgotten __CARL9170FW__ ifdef around
a private firmware-internal struct.
* GET_VAL macro helper
Very useful for extracting data out of the
bit-packed PHY registers.
* cosmetic changes
e.g.: _CCA_MINCCA_ to just _CCA_MIN_.
* version bump 1.8.8.3 -> 1.9.0.
