Add support for the SST sst26wf016, sst26wf032 and sst26wf064 flash IC:

sst26wf*** flash series block protection implementation differs from other
SST series, so we add implementation for sst26wf*** lock/unlock/is_locked
functions.

Add sst26wf016, sst26wf032 and sst26wf064 flash IC info to spi_flash_ids list.

Changes v4->v5:
 * Return EACCES when flash is locked instead of custom define (SF_LOCKED)
 * Add SST26_CTL_* prefix to sst27 lock ops enum.
 * Move all sst26 code inside of existing CONFIG_SPI_FLASH_SST #ifdef.

Changes v3->v4:
 * Make sst26_process_bpr() and sst26_lock_ctl() functions static.

Changes v2->v3:
 * Move SST26 command defenition to sf_internal.h
 * Merge sst26_set_bpr, sst26_clear_bpr and sst26_check_bpr functions
   into single sst26_process_bpr function.
 * Use SF_UNLOCKED/SF_LOCKED instead of magic numbers in
   sst26_lock_ctl()

Changes v1->v2:
 * Use generic defines from linux/sizes.h instead of custom ones.
