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

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.

ASoC: codecs: lpass-wsa-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.

ASoC: codecs: wsa-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.

ASoC: codecs: Check for error pointer after calling devm_regmap_init_mmio
Since the potential failure of the devm_regmap_init_mmio(), it will
return error pointer and be assigned to the regmap.
Then the error pointer will be dereferenced.
For example rx->regmap will be used in rx_macro_mclk_enable().
Therefore, it should be better to check it.

ASoC: codecs: lpass-wsa-macro: fix RX MIX input controls
Attempting to use the RX MIX path at 48kHz plays at 96kHz, because these
controls are incorrectly toggling the first bit of the register, which
is part of the FS_RATE field.

Fix the problem by using the same method used by the "WSA RX_MIX EC0_MUX"
control, which is to use SND_SOC_NOPM as the register and use an enum in
the shift field instead.
