RISC-V: KVM: Fix APLIC in_clrip[x] read emulation
The reads to APLIC in_clrip[x] registers returns rectified input values
of the interrupt sources.
A rectified input value of an interrupt source is defined by the section
"4.5.2 Source configurations (sourcecfg[1]–sourcecfg[1023])" of the
RISC-V AIA specification as:
rectified input value = (incoming wire value) XOR (source is inverted)
Update the riscv_aplic_input() implementation to match the above.
