Change interrogate command prototype to have command size
and returned buffer length.
This fixes the issue when command parameters are needed to
be passed to FW in addition to acx header as in the case with
get RSSI command, where role_id has to be passed.

Under this mode the chip is powered on including sdio
but no FW is downloaded and run, interrupts are not enabled, etc...
This mode is intended to allow RTTT to bridge sdio as a transport
to the chip.
Driver only provides sdio access using the dev_mem debugfs file.
Some fixes done to the code that ensures that PLT mode and normal
driver power mode (ifconfig/add_interface) are mutually excluded.

Pass the wdev from cfg80211 on to the driver as the vif
if given and it's valid for the driver.

When a function requests to recover, it would normally abort and will
not send any additional commands to the HW. However, other threads may
not be aware of the failure and could try to communicate with the HW
after a recovery was queued, but before the recovery work began.
Fix this by introducing an intermediate state which is set when recovery
is queued, and modify all state checks accordingly.

handle errors of nla_put() inside the if(nla_put...) {}
This makes the code simpler and clearer because:
we take advantage from the fact that we have only one nla_put
in our routines (so no real need for goto label).
this avoids ugly goto forward followed by goto backward.

this completes the calibrator based fem detect logic in driver:
driver starts (by calibrator) in plt_mode PLT_FEM_DETECT
wlcore inits and starts plt on wl12xx
wl12xx fetches fem number from firmware and stores it in wl->fem_manuf
wl12xx immediatly returns (doesn't start radio, etc...)
wlcore returns the fem_manuf to calibrator using WL1271_TM_ATTR_DATA
plt_mode is stopped

add wl->plt_mode that is used to indicate different plt
working modes: this will be used to implement calibrator side
auto fem detection where driver asks firmware to detect
the wlan fem radio type and returns it to calibrator.
this is not implemented yet and plt_modes: PLT_ON and
PLT_FEM_DETECT currently behave the same.

This command is buggy (doesn't take the mutex) and unused. Instead, the
"start_recovery" file is used for the same purpose. Remove the code but
keep the command constant to avoid breaking the testmode ABI.

Add register tables support in wlcore, add some new IO functions to
read and write to chip-specific register and data addresses. Move
some common register values from wl12xx to wlcore and add the
registers table to wl12xx.

In order to add chip-specific operations and prepare for future

Rename the wl12xx driver directory to wlcore as an initial step
towards the split of the driver into wlcore and wl12xx. We just
rename the directory first to keep git blame happy.
