[MIPS] Make I/O helpers more customizable
1. Move ioswab*() and __mem_ioswab*() to mangle-port.h. This gets rid
of CONFIG_SGI_IP22 from include/asm-mips/io.h.
2. Pass a virtual address to *ioswab*(). Then we can provide
mach-specific *ioswab*() and can do every evil thing based on its
argument. It could be useful on machines which have regions with
different endian conversion scheme.
3. Call __swizzle_addr*() _after_ adding mips_io_port_base. This
unifies the meaning of the argument of __swizzle_addr*() (always
virtual address). Then mach-specific __swizzle_addr*() can do every
evil thing based on the argument.
