hw/dma: sifive_pdma: permit 4/8-byte access size of PDMA registers

It's obvious that PDMA supports 64-bit access of 64-bit registers, and
in previous commit, we confirm that PDMA supports 32-bit access of
both 32/64-bit registers. Thus, we configure 32/64-bit memory access
of PDMA registers as valid in general.
