ASoC: max98504: Add max98504 speaker amplifier driver
This patch adds driver for the MAX98504 speaker amplifier. The MAX98504
is a high efficiency mono class D amplifier that features an integrated
boost converter with voltage and current sensing ADCs for Dynamic Speaker
Management.
This driver does not include support for the I2S DAI, as we wouldn't be
able to test such code in a hardware configuration where the amplifier
has only wired the analogue input.

[s.nawrocki: removed unused macro definitions, rewrote regulator supply
related parts, rewrote regmap configuration code, added support for speaker
enable and global chip enable through DAPM, rewritten as component driver,
added PDM DAI definition and TDM callbacks for PDM channels configuration]

Changes since v2:
- added parsing of the VBAT brownout DT properties,
- removed MAX98504_REG_SPEAKER_SOURCE_SELECT register initialization,
- removed unused macro definitions.
Changes since v1:
- none.
Changes since initial version:
- added regulator supply handling,
- added DAPM widges for speaker source selection,
- added PDM DAI definition and TDM callbacks for setting up active
PDM Tx channels and I/V sense ADC data mapping,
- removed all optional DT properties, added regulator supply properties
in the DT binding.
