The TC9595 reset GPIO is SAI1_RXC / GPIO4_IO01, fix the DT accordingly.
The SAI5_RXD0 / GPIO3_IO21 is thus far unused TC9595 interrupt line.

The i.MX8MP DHCOM SoM production rev.200 is populated with M24C32-D

address. Describe the page in DT to make it available.

The current imx8mp-dhcom-som.dtsi describes prototype rev.100 SoM,
update the DT to describe production rev.200 SoM which brings the
following changes:
- Fast SoC GPIOs exposed on the SoM edge connector
- Slow GPIOs like component resets moved to I2C GPIO expander
- ADC upgraded from TLA2024 to ADS1015 with conversion interrupt
- EEPROM size increased from 256 B to 4 kiB

i.MX8MP DHCOM SoM
The reset-gpio is connected to WL_REG_EN signal of the WiFi MAC, the
mmc-pwrseq-simple driver is better suited to operate this signal as
it is tied to the slot instead of the MAC, and it can enable the MAC
before the brcmfmac driver binds to it. Make use of the MMC power
sequencer.

Add SAI I2S and audio bindings on MX8MP DHCOM PDK2 and PDK3.
The VDDA is supplied from on-carrier-board regulator, the VDDIO
is supplied from always-on on-SoM regulator. Except for different
I2C bus used to connect the codec, the implementation is virtually
identical on both carrier boards.
Align regulator-avdd name to regulator-3p3vdd on PDK3, since this
is the VDDA supply and it is the same on both carrier boards.

The i.MX8MP DHCOM SoM may come with either external RGMII PHY or
LAN8740Ai RMII PHY on the SoM attached to FEC MAC. Add pin mux
settings for both options, so that DT overlay can override these
settings on SoM variant with the LAN8740Ai PHY.

The VSELECT pin is configured as MX8MP_IOMUXC_GPIO1_IO04__USDHC2_VSELECT
and not as a GPIO, drop the bogus sd-vsel-gpios property as the eSDHC
block handles the VSELECT pin on its own.

Use PLL1_80M instead of PLL3 to drive UART2 clock divided down to 80 MHz
instead of 64 MHz to obtain suitable block clock for exact 4 Mbdps, which
is the maximum supported baud rate by the muRata 2AE BT UART.
The difference here is that at 64 MHz UART block clock, the clock with are
divided by 16 (due to oversampling) to 4 MHz and the baud rate generator
then needs to be set to UBIR+1/UBMR+1 = 1/1 to yield 4 Mbdps . In case of
80 MHz UART block clock divided by 16 to 5 MHz, the baud rate generator
needs to be set to UBIR+1/UBMR+1 = 4/5 to yield 4 Mbdps .
Both options are valid and yield the same result, except using the PLL1_80M
output requires fewer clock tree changes, since the PLL1 already generates
the 80 MHz usable for UART, which frees the PLL3 for other uses.

The "regulator-compatible" property is deprecated and unused, as the
match happens on the node name in Linux of_regulator_match() in case
the property is not present. Drop the deprecated property from DT.

The i.MX8MP DHCOM SoM does contain muRata 2AE WiFi+BT chip, bind the
bluetooth to UART2 using btbcm and hci_bcm drivers. Use PLL3 to drive
UART2 clock divided down to 64 MHz to obtain suitable block clock for
exact 4 Mbdps, which is the maximum supported baud rate by the muRata
