I see you have changed the driver file name from irq-riscv-plic to 
irq-riscv-sifive along with default Y for SIFIVE_PLIC. I guess it was 
done because PLIC register spec is SIFIVE specific rather than RISC-V.

But can we keep the new kconfig option "SIFIVE_PLIC" enabled in 
driver/irqchip/Kconfig or arch/riscv/Kconfig for now to avoid breakage 
without linux_defconfig update.

With the config enabled, Qemu virt machine booting has no issues with 
riscv-irq-simple.2 branch. I am still looking at the crash from the 
hardware.
