492fe974fe ASoC: codecs: lpass-rx-macro: add support for SM8550 
Add support for the RX macro codec on Qualcomm SM8550.  SM8550 does not
use NPL clock, thus add flags allowing to skip it.

a4a3203426 ASoC: codecs: lpass: fix the order or clks turn off during suspend 
The order in which clocks are stopped matters as some of the clock
like NPL are derived from MCLK.

Without this patch, Dragonboard RB5 DSP would crash with below error:
 qcom_q6v5_pas 17300000.remoteproc: fatal error received:
 ABT_dal.c:278:ABTimeout: AHB Bus hang is detected,
 Number of bus hang detected := 2 , addr0 = 0x3370000 , addr1 = 0x0!!!

Turn off  fsgen first, followed by npl and then finally mclk, which is exactly
the opposite order of enable sequence.

5b06877205 ASoC: codecs: lpass-rx-macro: Convert to platform remove callback returning void 
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

e762143437 ASoC: codecs: lpass: fix incorrect mclk rate 
For some reason we ended up with incorrect mclk rate which should be
1920000 instead of 96000, So far we were getting lucky as the same clk
is set to 192000 by wsa and va macro. This issue is discovered when there
is no wsa macro active and only rx or tx path is tested.
Fix this by setting correct rate.

   Intel systems.
 - Some building blocks for use in forthcoming Intel AVS driver for
   legacy Intel DSP firmwares.
 - Support for AMD PDM, Atmel PDMC, Awinic AW8738, i.MX cards with
   TLV320AIC31xx, Intel machines with CS35L41 and ESSX8336, Mediatek

eaba113430 ASoC: codecs: rx-macro: setup soundwire clks correctly 
For SoundWire Frame sync to be generated correctly we need both MCLK
and MCLKx2 (npl). Without pm runtime enabled these two clocks will remain on,
however after adding pm runtime support its possible that NPl clock could be
turned off even when SoundWire controller is active.

Fix this by enabling mclk and npl clk when SoundWire clks are enabled.
