Nikita Kiryanov 43e568c4ae arm: am437x: cm-t43: set MPU and CORE voltages on boot 
During boot, U-Boot raises the CPU frequency but the CORE and MPU regulators
are not updated. This is not a problem in cold boot since the default values
that the pmic outputs are correct, but if Linux were to switch the module to a
low power OPP, the new voltage values will be retained after a reboot and the
module will likely hang once U-Boot raises the CPU frequency back up.

Set both CORE and MPU regulators to to 1.1V on boot.
