microblaze: cache: introduce Kconfig options for icache/dcache sizes

Browse Source 
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().

This fallback size will be used when no dcache info can be found in
the device tree, or when the data cache is flushed very early in the
boot process, before device tree is available.
