irqchip/loongson-pch-msi: Adjust irqchip driver for 32BIT/64BIT

Browse source 
irq_domain_alloc_fwnode() takes a parameter with the phys_addr_t type.
Currently the code passe acpi_pchmsi->msg_address to it.

This can only work on 64BIT platform because its type is u64, so cast it to
phys_addr_t and then the driver works on both 32BIT and 64BIT platform.

[ tglx: Make the cast explicit and fixup coding style. ]
