When submitting a GPIO driver I was suggested to not depend on architecture symbol and add soc-specific ones to arch/ first. [0] I still need to polish the clock/reset driver a bit before submitting them. Without a clock driver I can't really submit a dts with meaningful content.

Siflower RISC-V SoCs, including SF21A6826, SF21H8898 and some other upcomping chips, are RISC-V chips with T-Head C908 cores for home routers and gateways. Add a Kconfig entry named ARCH_SIFLOWER for them. Notably these chips uses ARM PL011 for UART. ARM_AMBA is selected for its driver.
