unicore32: replace unicore32-specific iomap functions with generic lib implementation

1. define and enable CONFIG_GENERIC_IOMAP
2. define unicore32-specific PCI_IOBASE for asm-generic/io.h
3. define HAVE_ARCH_PIO_SIZE and unicore32-specific PIO_* macros
4. remove all unicore32-specific iomap functions
