spi-geni-qcom: Add new interfaces and utilise them
Merge series from Vijaya Krishna Nivarthi <quic_vnivarth@quicinc.com>:
A "known issue" during implementation of SE DMA for spi geni driver was
that it does DMA map/unmap internally instead of in spi framework.
Current patches remove this hiccup and also clean up code a bit.
Testing revealed no regressions and results with 1000 iterations of
reading from EC showed no loss of performance.
