Add the support of SYSCFG clock used by syscon driver
to prepare the clock management of STM32MP_SYSCON_SYSCFG.
This clock is already defined in kernel device tree,
stm32mp151.dtsi but not yet supported in the syscon driver:
syscfg: syscon@50020000 {
compatible = "st,stm32mp157-syscfg", "syscon";
reg = <0x50020000 0x400>;
clocks = <&rcc SYSCFG>;
};
It is safe to support this clock in U-Boot driver with
RCC_MC_APB3ENSETR, Bit 11 SYSCFGEN: SYSCFG peripheral clocks
enable.
