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.

sf: Move SPI flash drivers to defconfig
...
There are already Kconfig options for SPI flash drivers, but we
have not moved them from config.h to defconfig files. This commit
does this in a batch.
