Subject: [PATCH v2 3/3] RISC-V: stop selecting SIFIVE_PLIC at the SoC level

From: Conor Dooley <conor.dooley@...rochip.com>

The SIFIVE_PLIC driver is used by all current RISC-V SoCs & will be,
where possible, used for future implementations. Rather than having each
driver select the option on a case-by-case basis, do so at the arch
level.
