When receiving data in cyclic mode from PDMA peripherals, where reload
count is set to infinite, any TR in the set can potentially be the last
one of the overall transfer. In such cases, the EOP flag needs to be set
in each TR and PDMA's Static TR "Z" parameter should be set, matching
the size of the T... | ```diff

Configs like the ones coming from the MMC subsystem will have either
'src' or 'dst' zeroed, resulting in an unknown bus width. This will bail
out on the RZ DMA driver because of the sanity check for a valid bus
width. Reorder the code, so that the check will only be applied when the
corresponding addre... | ```diff
