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.

Be careful here, CONFIG_SYS_CACHELINE_SIZE is established all over the u-boot, so this might cause build breakage. You should keep some compatibility CONFIG_SYS_CACHELINE_SIZE entry and set it to default to SYS_DCACHE_LINE_SIZE , since it's mostly used for DMA anyway.
Marek is right. Some USB drivers still use CONFIG_SYS_CACHELINE_SIZE instead of ARCH_DMA_MINALIGN so CONFIG_SYS_CACHELINE_SIZE needs to be kept as Kconfig symbol.
