MIPS: Support 36-bit iomem on 32-bit Au1x00
I believe these changes are needed on Alchemy SoCs in order to
use iomem above 4G with the usual platform_device machinery:
- Set CONFIG_ARCH_PHYS_ADDR_T_64BIT to make resource_size_t 64-bit.
- Increase IOMEM_RESOURCE_END so that platforms can register resources.
