riscv: plat-virt: Let CFG_RISCV_PLIC be build time configurable

RISC-V has several standard interrupt controllers supported by QEMU virtual platform. This commit removes enforcement of CFG_RISCV_PLIC so that CFG_RISCV_PLIC can be build time configurable for developer. Signed-off-by: Alvin Chang <[email protected]>
