[MIPS] Fix IP32 breakage
- suppress master aborts during config read
- set io_map_base
- only fixup end of iomem resource to avoid failing request_resource
in serial driver
- killed useless setting of crime_int bit, which caused wrong interrupts
- use physcial address for serial port platform device and let 8250
driver do the ioremap
