Mostly motivated by PP needing CACHEALIGN_SIZE in linker scripts, which can't include system.h, so move these to cpu.h instead. Also gets rid of the default 32 byte line size that was used if the target didn't define alignment itself. RK24xx, DM320, and JZ4740 were missing this but have been confirmed (from datasheets) to use 32-byte cache lines. Add checks to make sure the macros are appropriately (un)defined based on the HAVE_CPU_CACHE_ALIGN define, and make sure their values are consistent when they are defined. Disable HAVE_CPU_CACHE_ALIGN for hosted targets since it arguably doesn't matter if there's a cache, if we aren't responsible for cache maintenance. A few files in rbcodec use CACHEALIGN_SIZE, but these can be converted to MEM_ALIGN_SIZE, which is identical to CACHEALIGN_SIZE if the latter is defined. On other targets, it aligns to at least sizeof(intptr_t). Change-Id: If8cf8f6ec327dc3732f4cd5022a858546b9e63d6
