display5: Support for the emergency PAD pressing
To enter the special mode, one needs to short cut two pads with e.g. screw
driver.
After power up the SPL will execute u-boot in which proper actions will be
taken.
It is worth noting that we do not alter envs (even the BOOT_FROM variable)
and unconditionally go to recovery.
