EFS: Perform EFS even if flash WP is enabled
This patch removes flash WP check in the EFS main. It means even
if the SPI flash is not write protected, it performs EFS.
This allows dogfood devices to boot just like normal devices.
BUG=b:74983574
BRANCH=none
TEST=Boot Fizz. Verify EFS works as expected.
HW_WP=0, SW_WP=0: No EFS
HW_WP=0, SW_WP=1: No EFS
HW_WP=1, SW_WP=0: EFS is performed (Dogfood devices)
HW_WP=1, SW_WP=1: EFS is performed (Normal devices)
