c331b344d5 wlcore/wl12xx: add plt_init op and move the code to wl12xx
PLT mode needs to be initialized differently for each chip.  This
patch adds an operation to init PLT and moves the existing PLT
initialization into the wl12xx driver.

a9c130d522 wl18xx: add board type module argument
Different board types (ie. FPGA, HDK and DVP/EVB) require slightly
different init configuration options.  Since we cannot probe the type

types, with DVP/EVB as the default, and uses this value where needed.

f380f2c4a1 wl1251: fix oops on early interrupt
This driver disables interrupt just after requesting it and enables it
later, after interface is up. However currently there is a time window
between request_irq() and disable_irq() where if interrupt arrives, the
driver oopses because it's not yet ready to process it. This can be
reproduced by inserting the module, associating and removing the module
multiple times.

Eliminate this race by setting IRQF_NOAUTOEN flag before request_irq().
