Removed the use of two hardcoded interfaces and added support to
add/remove the network interfaces dynamically.
Now the driver will have single default interface with name 'wlan0' and
later other interface can be added from user space application e.g
using 'iw add' command.
Also taken care to maintain 'wilc_vif' as part of 'net_device'
private data and 'wilc' struct as 'wiphy' private data.

The masking update of pkg_offset is redundant as the updated
value is never read and pkg_offset is re-assigned on the next
iteration of the loop. Clean this up by removing the redundant
assignment.

usleep_range() is called in non-atomic context so there is little point
in setting min==max as the jitter of hrtimer is determined by interruptions
anyway. usleep_range can only perform the intended coalescence if some
room for placing the hrtimer is provided. Given the range of milliseconds
the delay will be 2+ anyway - so make it 2-2.5 ms which gives hrtimers
space to optimize without negatively impacting performance.

Use mutex lock to protect the issuing of wid cmd to the firmware.

single module"
The TODO item named "make spi and sdio components coexist in one build"
was apparently addressed a long time ago, but never removed from the
TODO file. However, the new patch that tries to address it actually
makes it worse again by duplicating the common parts of the driver into
two separate modules rather than sharing them. This also introduces a
build regression when one of the two is built-in while the other is a
loadable module:
drivers/staging/wilc1000/wilc_debugfs.o:(.data+0x10): undefined reference to `__this_module'
Reverting the patch makes it build again. I'm leaving the TODO file
modification though, as there is nothing left to do for this item.
A related problem however still seems to exist: one still cannot have
multiple concurrent instances of wilc1000 devices present in the
system, as there are lots of shared global variables such as
host_interface.c:static struct wilc_vif *periodic_rssi_vif;
wilc_sdio.c:static struct wilc_sdio g_sdio;
wilc_wlan.c:static enum chip_ps_states chip_ps_state = CHIP_WAKEDUP;
wilc_wlan.c:static u32 pending_acks;
wilc_wfi_cfgoperations.c:int wilc_connecting;
In order to have multiple instances working (sdio, spi, or mixed),
all such variables need to be dynamically allocated per instance and
stored in 'struct wilc' or one of the structures referenced by it.
