IKG5-1471: Change the WLAN driver from dynamic module to static module

Change the WLAN driver from dynamic module to static module, move it
from hardware/ti/wlan to kernel drivers.

This driver is pulled from https://github.com/TI-OpenLink/wl18xx by
the latest commit as the following.

    wlcore: decrease warning verbosity during recovery

    Silently ignore repetitive scheduling of recovery work and commands
    being passed to the bus when the HW is not available. This can happen
    many times during recovery and slow it down. It also spams the kernel
    logs.
