[PATCH 1/2] hw/intc/riscv_aplic.c fix non-KVM --enable-debug build

[Daniel Henrique Barboza]

Commit 6df0b37e2ab breaks a --enable-debug build in a non-KVM
environment with the following error:

/usr/bin/ld: libqemu-riscv64-softmmu.fa.p/hw_intc_riscv_aplic.c.o: in function 
`riscv_kvm_aplic_request':
./qemu/build/../hw/intc/riscv_aplic.c:486: undefined reference to `kvm_set_irq'
collect2: error: ld returned 1 exit status

This happens because the debug build will poke into the
'if (is_kvm_aia(aplic->msimode))' block and fail to find a reference to
the KVM only function riscv_kvm_aplic_request().

Make riscv_kvm_aplic_request() a no-op if we're not building KVM.

Fixes: 6df0b37e2ab ("target/riscv: update APLIC and IMSIC to support KVM AIA")
