ASoC: mediatek: mt8183-afe-pcm: Support >32 bit DMA addresses

Browse Source 
The AFE DMA hardware supports up to 34 bits for DMA addresses. This is
missing from the driver and prevents reserved memory regions from
working properly when the allocated region is above the 4GB line.

Fill in the related register offsets for each DAI, and also set the
DMA mask. Also fill in the LSB end register offsets for completeness.
