ASoC: Intel: boards: fix unmet dependency on PINCTRL

ASoC: Intel: boards: fix unmet dependency on PINCTRL

This reverts commit c073f0757663 ("ASoC: Intel: sof_sdw: select PINCTRL_CS42L43 and SPI_CS42L43")

Currently, SND_SOC_INTEL_SOUNDWIRE_SOF_MACH selects PINCTRL_CS42L43
without also selecting or depending on PINCTRL, despite PINCTRL_CS42L43
depending on PINCTRL.

See the following Kbuild warning:

WARNING: unmet direct dependencies detected for PINCTRL_CS42L43
  Depends on [n]: PINCTRL [=n] && MFD_CS42L43 [=m]
  Selected by [m]:
  - SND_SOC_INTEL_SOUNDWIRE_SOF_MACH [=m] && SOUND [=y] && SND [=m] && SND_SOC [=m] && SND_SOC_INTEL_MACH [=y] && (SND_SOC_SOF_INTEL_COMMON [=m] || !SND_SOC_SOF_INTEL_COMMON [=m]) && SND_SOC_SOF_INTEL_SOUNDWIRE [=m] && I2C [=y] && SPI_MASTER [=y] && ACPI [=y] && (MFD_INTEL_LPSS [=n] || COMPILE_TEST [=y]) && (SND_SOC_INTEL_USER_FRIENDLY_LONG_NAMES [=n] || COMPILE_TEST [=y]) && SOUNDWIRE [=m]

In response to v1 of this patch [1], Arnd pointed out that there is
no compile-time dependency sof_sdw and the PINCTRL_CS42L43 driver.
After testing, I can confirm that the kernel compiled with
SND_SOC_INTEL_SOUNDWIRE_SOF_MACH enabled and PINCTRL_CS42L43 disabled.

This unmet dependency was detected by kconfirm, a static analysis
tool for Kconfig.
