microblaze: cache: introduce Kconfig options for icache/dcache sizes
Replace XILINX_DCACHE_BYTE_SIZE macro with two Kconfig symbols for
instruction and data caches sizes, respectively:
CONFIG_XILINX_MICROBLAZE0_ICACHE_SIZE
CONFIG_XILINX_MICROBLAZE0_DCACHE_SIZE
Also, get rid of the hardcoded value in icache_disable().
