0678e9f29c2301d0a1afc8d01a78cdfa7ad2ddbd hw/intc/riscv_aplic: Fix in_clrip[x] read emulation
The reads to in_clrip[x] registers return 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_read_input_word() implementation to match the above.
Fixes: e8f79343cfc8 ("hw/intc: Add RISC-V AIA APLIC device emulation")
