soc: qcom: geni-se: Add M_TX_FIFO_NOT_EMPTY bit definition

According to the docs I have, bit 21 of the status register is
asserted when the FIFO is _not_ empty. Add the definition.

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.
