For the delay of 10 uSec or more usleep_range is prefered.
Unlike udelay, sleep_range avoids large number of undesired
interrupts.

alloc failures use dump_stack so emitting an additional
out-of-memory message is an unnecessary duplication.

Remove the allocation failure messages.

Free SKBs allocated during multiport aggrgation setup when RX
multiport aggregation fails in the middle. With this handling
freeing SKB in mwifiex_process_int_status() for failure case
is removed.

Also handles single RX transaction failure.

Since the auto deep sleep mode has been enabled at driver init time
we should disable it at driver unloading to shutdown the function
gracefully.

1) Avoid global adapter pointer usage
a) in sdio.c by moving some code from mwifiex_cleanup_module() to
mwifiex_sdio_remove().
b) in main.c by passing an extra parameter to few functions.
2) Add new variable "user_rmmod" to identify if mwifiex_sdio_remove()
callback function is called in card removal or rmmod context. These
code changes are adapted from Libertas driver.
3) Remove unnecessary NULL pointer check for "func" pointer in
mwifiex_sdio_remove().

For SD8787 A0/A1 chipsets we use the default firmware image
file 'mrvl/sd8787_uapsta.bin'. So the chip rev id variable
is removed.

The global variable fw_name is moved to adapter structure
so that we can support a different interface, such as PCIe,
in future.
