GuanXuetao 1cf46c42d7 unicore32: modify io_p2v and io_v2p macros, and adjust PKUNITY_mmio_BASEs
1. remove __REG macro
2. add (void __iomem *) to io_p2v macro
3. add (phys_addr_t) to io_v2p macro
4. add PKUNITY_AHB_BASE and PKUNITY_APB_BASE definitions
5. modify all PKUNITY_mmio_BASEs from physical addr to virtual addr
6. adjust prefix macro for all usage of PKUNITY_mmio_BASEs
