target/riscv: update APLIC and IMSIC to support KVM AIA
KVM AIA can't emulate APLIC only. When "aia=aplic" parameter is passed,
APLIC devices is emulated by QEMU. For "aia=aplic-imsic", remove the
mmio operations of APLIC when using KVM AIA and send wired interrupt
signal via KVM_IRQ_LINE API.
After KVM AIA enabled, MSI messages are delivered by KVM_SIGNAL_MSI API
when the IMSICs receive mmio write requests.
