m32r: Add ioreadXX/iowriteXX big-endian mmio accessors
commit c627f2ceb6
("serial: 8250: Add support for big-endian MMIO accesses")
added support for 32-bit big-endian mmio to the 8250 driver. Support for
ioreadXXbe/iowriteXXbe io accessors was missing from m32r arch, which caused
build errors.
Add trivial macro mmio accessors.
