ASoC: qcom: lpass-cpu: Remove bit clock state check

No need of BCLK state maintenance from driver side as
clock_enable and clk_disable API's maintaing state counter.

One of the major issue was spotted when Headset jack inserted
while playback continues, due to same PCM device node opens twice
for playaback/capture and closes once for capture and playback continues.

It can resolve the errors in such scenarios.

ASoC: qcom: lpass: Fix out-of-bounds DAI ID lookup

The "dai_id" given into LPAIF_INTFDMA_REG(...) is already the real
DAI ID, not an index into v->dai_driver. Looking it up again seems
entirely redundant.

For IPQ806x (and SC7180 since commit 09a4f6f5d21c
("ASoC: dt-bindings: lpass: Fix and common up lpass dai ids") this is
now often an out-of-bounds read because the indexes in the "dai_driver"
array no longer match the actual DAI ID.

ASoC: qcom: Fix enabling BCLK and LRCLK in LPAIF invalid state

Fix enabling BCLK and LRCLK only when LPAIF is invalid state and
bit clock in enable state.
In device suspend/resume scenario LPAIF is going to reset state.
which is causing LRCLK disable and BCLK enable.
Avoid such inconsitency by removing unnecessary cpu dai prepare API,
which is doing LRCLK enable, and by maintaining BLCK state information.

ASoC: qcom: lpass-cpu: Make I2S SD lines configurable

The LPASS hardware allows configuring the MI2S SD lines to use
when playing/recording audio. However, at the moment the lpass-cpu
driver has SD0 hard-coded for mono/stereo (or additional fixed
SD lines for more channels).

For weird reasons there seems to be hardware that uses one of the
other SD lines for mono/stereo. For example, some Samsung devices
use an external Speaker amplifier connected to Quaternary MI2S.
For some reason, the SD line for audio playback was connected to
SD1 rather than SD0. (I have no idea why...)
At the moment, the lpass-cpu driver cannot be configured to work
for the Speaker on these devices.

The q6afe driver already allows configuring the MI2S SD lines
through the "qcom,sd-lines" device tree property, but this works
only when routing audio through the ADSP.

This commit adds a very similar configuration for the lpass-cpu driver.
It is now possible to add additional subnodes to the lpass device in
the device tree, to configure the SD lines for playback and/or capture.
E.g. for the Samsung devices mentioned above:

&lpass {
dai@3 {
reg = <MI2S_QUATERNARY>;
qcom,playback-sd-lines = <1>;
};
};

qcom,playback/capture-sd-lines takes a list of SD lines (0-3)
in the same format as the q6afe driver. (The difference here is that
q6afe has separate DAIs for playback/capture, while lpass-cpu has one
for both...)

For backwards compatibility with older device trees, the lpass-cpu driver
defaults to LPAIF_I2SCTL_MODE_8CH if the subnode for a DAI is missing.
This is equivalent to the previous behavior: Up to 8 channels can be
configured, and SD0/QUAT01 will be chosen when setting up a stream
with fewer channels.

This allows the speaker to work on Samsung MSM8916 devices
that use an external speaker amplifier.

ASoC: qcom: add generic bit masks for RDMA and WRDMA

This patch adds generic masks for accessing bits in rdma/wrdma
registers. Doing this would simplify the driver and adding capture
support would be much simpler. Also there is no point in having same
bit masks for bits in both rdma and wrdma registers.

This patch also deletes the RDMA specific bit masks and makes the code
use the generic bit masks.
