Luciano Coelho df472894ab wlcore: add module parameter to dump SDIO reads and writes
In some cases we may want to dump all the SDIO data in order to get
detailed information for debugging the communication with the
firmware.

Add printks to dump the data and a module parameter to enable/disable
it.

Luciano Coelho 1ddbc7d4c7 wl18xx: add a module parameter to control 11a support
In wl18xx we don't have an NVS yet, so we need to control whether 11a
is supported with a module parameter for now.  11a support is enabled
by default and can be changed by setting enable_11a to false when
loading the module.

Arik Nemtsov 0afd04e5e5 wlcore/wl12xx/18xx: split fw_status struct into two
The number of RX packet descriptors may vary from chip to chip and
in different firmware versions.  Unfortunately, the array that
contains the actual descriptors is in the middle of the fw_status
structure.  To manage this, we split the struct into two so we can
calculate the offset of what comes after the array and access the last
elements more easily.

[Changed the STATUS_LEN macro to be placement agnostic - Arik]
