irqchip/loongson-liointc: Adjust irqchip driver for 32BIT/64BIT

Browse Source 
irq_domain_alloc_fwnode() takes a parameter with the phys_addr_t type.
Currently the code passes acpi_liointc->address to it.

This can only work on 64BIT platforms 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 use the casted address as argument for
  	liointc_init() which takes a phys_addr_t as well. Sigh... ]
