MIPS: Split I & D cache line size config
Allow L1 Icache & L1 Dcache line size to be specified separately, since
there's no architectural mandate that they be the same. The
[id]cache_line_size functions are tidied up to take advantage of the
fact that the Kconfig entries are always present to simply check them
for zero rather than needing to #ifdef on their presence.

[removed CONFIG_SYS_CACHELINE_SIZE in include/configs/pic32mzdask.h]
