4b8f489289 arm: am437x: cm-t43: bring back BOOTDELAY feature
Commit 755324 (configs: Use config_distro_defaults.h in ti_armv7_common.h)
made ti_armv7_common.h include config_distro_defaults.h. This breaks the
bootdelay feature in cm_t43 because now the
  - #include ti_armv7_common.h (#define CONFIG_BOOTDELAY 1)
  - #undef CONFIG_BOOTDELAY
  - #include config_distro_defaults.h (#define CONFIG_BOOTDELAY 2)
dance in cm_t43.h is no longer valid and in fact leads to CONFIG_BOOTDELAY
not being defined.

Adapt the config file to the new inclusion hierarchy.

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.

68d5342017 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.
