SPEAr: Enable CONFIG_SYS_FLASH_PROTECTION

Browse source 
This patch enables flash protection(lock/unlock) for CFI devices.
This is necessary because the Parallel NOR flash connected on the spear
boards, M28W64, can be locked/unlocked on a sector basis. Moreover, all its
sectors are in locked state at reset and these have to be unlocked explicitly
before being erased or written.
