ARM: dts: stm32: Switch defconfig to SPL for DH STM32MP13xx DHCOR DHSBC
Update defconfig to make use of U-Boot SPL to initialize DH STM32MP13xx
DHCOM DHSBC SoM and board. This is largely a move of SPL enablement from
DH STM32MP15xx DHSOM defconfigs into generic DH STM32MP1xx defconfig .
Support for SPI NOR chips which are not used on STM32MP13xx DHCOR are
moved into STM32MP15xx DHSOM defconfigs. Changes to STM32MP13xx DHCOR
defconfig then enable SPL support, CCF in SPL to configure clock, pin
configuration support in SPL, and OpTee OS start support in U-Boot.
