[MTD] Unlocking all Intel flash that is locked on power up.
Patch for unlocking all Intel flash that has instant locking on power up.
The patch has been tested on Intel M18, P30 and J3D Strata Flash.
1. The automatic unlocking can be disabled for a particular partition
in the map or the command line.
a. For the bit mask in the map it should look like:
.mask_flags = MTD_POWERUP_LOCK,
b. For the command line parsing it should look like:
mtdparts=0x80000(bootloader)lk
2. This will only unlock parts with instant individual block locking.
Intel parts with legacy unlocking will not be unlocked.
