Jim Shu 1aae4a12da hw/intc: sifive_plic: change interrupt priority register to WARL field 
PLIC spec [1] requires interrupt source priority registers are WARL
field and the number of supported priority is power-of-2 to simplify SW
discovery.

Existing QEMU RISC-V machine (e.g. shakti_c) don't strictly follow PLIC
spec, whose number of supported priority is not power-of-2. Just change
each bit of interrupt priority register to WARL field when the number of
supported priority is power-of-2.
