parisc: Change L1_CACHE_BYTES to 16
...
Change L1_CACHE_BYTES to 16 bytes.
Tested for 16 days on rp3440.
Additional remarks from Helge Deller:
Saves ~17 kb of kernel code/data and gives a slight performance improvement in
various test cases.

dma-mapping: parisc: set ARCH_DMA_MINALIGN
...
Architectures that handle DMA-non-coherent memory need to set
ARCH_DMA_MINALIGN to make sure that kmalloc'ed buffer is DMA-safe: the
buffer doesn't share a cache with the others.
