soc: qcom: geni-se: Add interfaces geni_se_tx_init_dma() and geni_se_rx_init_dma()
...
The geni_se_xx_dma_prep() interfaces necessarily do DMA mapping before
initiating DMA transfers. This is not suitable for spi where framework
is expected to handle map/unmap.
Expose new interfaces geni_se_xx_init_dma() which do only DMA transfer.

soc: qcom: geni-se: Update Tx and Rx fifo depth based on QUP HW version
...
From QUP HW Version 3.10 and above the Tx and Rx
fifo depth bits are increased to 23:16 bits from
21:16 bits in SE_HW_PARAM registers accomodating
256bytes of fifo depth.
Updated geni_se_get_tx_fifo_depth and
geni_se_get_rx_fifo_depth to retrieve right fifo
depth based on QUP HW version.

Move include/linux/qcom-geni-se.h to include/linux/soc/qcom/geni-se.h.
This removes 1 of a few remaining Qualcomm-specific headers into a more
approciate subdirectory under include/.
