[PATCH v2 1/3] riscv: add Siflower RISC-V SoC family Kconfig support

[Chuanhong Guo <gch981213@gmail.com>]

Siflower RISC-V SoCs, including SF21A6826 and SF21H8898, 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.
