rdma_ch_bit_map can be reused for wrdma channel allocations as wrdma
channel numbering start after rdma channel numbers.
With capture support referring rdma_ch_bit_map for wrdma channel allocation
is confusing, so renaming rdma_ch_bit_map to dma_ch_bit_map makes sense.

This patch updates the internal dma allocation callbacks to take the
stream direction so that it can allocate channels suitable for that
stream direction. Before the capture support this was not necessary.

This patch renames rdmactl_audif_start to dmactrl_audif_start as this
is common for both rdma and wrdma. Without this patch the name would be
bit misleading to the readers.

This patch adds apq8016 lpass driver support. APQ8016 has 4 MI2S which
can be routed to one internal codec and 2 external codec interfaces.
Primary, Secondary, Quaternary I2S can do Rx(playback) and Tertiary and
Quaternary can do Tx(capture).

This patch adds dma channel bit mask to lpass data to keep track of dma
channel allocations. This flag would be used in apq8016 lpass driver.

start after an offset of 1.

This patch adds support to allow bitclk and osrclk per i2s dai port.
on APQ8016 there are 4 i2s ports each one has its own bit clks.

This patch removes hardcoded dma channel value in lpass driver, Now the
dma channel allocation happens in the SOC specific layer. This will
allow different LPASS integrations to use the lpass driver in more
generic way.

This patch tries to make the lpass driver more generic by moving the
ipq806x specific bits out of the cpu and platform driver, also allows the
SOC specific drivers to add the correct register offsets.
This patch also renames the register definition header file into more
generic header file.
