Adrian Salido c4c592b2c1 driver core: platform: fix race condition with driver_override 
commit 6265539776 upstream.

The driver_override implementation is susceptible to race condition when
different threads are reading vs storing a different driver override.
Add locking to avoid race condition.

Fixes: 3d713e0e38 ("driver core: platform: add device binding path 'driver_override'")
