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.

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.
