irqchip/riscv-imsic: Fix output text of base address
...
The "per-CPU IDs ... at base ..." info log is outputting a physical
address, not a PPN.

irqchip/riscv-imsic: Add ACPI support
...
RISC-V IMSIC interrupt controller provides IPI and MSI support.
Currently, DT based drivers setup the IPI feature early during boot but
defer setting up the MSI functionality. However, in ACPI systems, PCI
subsystem is probed early and assume MSI controller is already setup.
Hence, both IPI and MSI features need to be initialized early itself.

irqchip/riscv-imsic: Fix boot time update effective affinity warning
...
Currently, the following warning is observed on the QEMU virt machine:
genirq: irq_chip APLIC-MSI-d000000.aplic did not update eff. affinity mask of irq 12
The above warning is because the IMSIC driver does not set the initial
value of effective affinity in the interrupt descriptor. To address this,
initialize the effective affinity in imsic_irq_domain_alloc().

irqchip/riscv-imsic: Add device MSI domain support for PCI devices
...
The Linux PCI framework supports per-device MSI domains for PCI devices
so extend the IMSIC driver to allow PCI per-device MSI domains.

irqchip/riscv-imsic: Add device MSI domain support for platform devices
...
The Linux platform MSI support allows per-device MSI domains so add
a platform irqchip driver for RISC-V IMSIC which provides a base IRQ
domain with MSI parent support for platform device domains.
The IMSIC platform driver assumes that the IMSIC state is already
initialized by the IMSIC early driver.
