Merge patch series "RISC-V interrupt controller select cleanup"

Conor Dooley <conor@kernel.org> says:

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

Submitted a patch yesterday defaulting the SiFive PLIC driver to
enabled [0], and in the ensuing conversation Marc suggested just doing a
select at the arch level and dropping the user selectability completely.

* b4-shazam-merge:
  RISC-V: stop selecting SIFIVE_PLIC at the SoC level
  irqchip/riscv-intc: remove user selectability of RISCV_INTC
  irqchip/sifive-plic: remove user selectability of SIFIVE_PLIC
