hw/riscv: Select MSI_NONBROKEN in SIFIVE_PLIC

hw/pci/Kconfig says MSI_NONBROKEN should be selected by interrupt
controllers regardless of how MSI is implemented. msi_nonbroken is
initialized to true in sifive_plic_realize().

Let SIFIVE_PLIC select MSI_NONBROKEN and drop the selection from
RISC-V machines.
