Fix the following dtbs_check warning on all of i.MX8M variants:
"
opp-table: Unevaluated properties are not allowed ('opp-25M', 'opp-100M', 'opp-750M' were unexpected)
"
Using the following command:
"
$ sed -i '/opp-[0-9]\+M/ s@M {@000000 {@' arch/arm64/boot/dts/freescale/imx8m*
"
The Documentation/devicetree/bindings/opp/opp-v2-base.yaml expects the OPP
subnode names to be full frequency listings in Hz without unit suffixes.
Only the i.MX8M DTs are affected per "git grep 'opp-[0-9]\+M'", so fix them.

Before commit 0e30f47232ab5 ("mtd: spi-nor: add support for DTR protocol"),
for all PP command, it only support 1-1-1 mode, no matter the tx setting
in dts. But after the upper commit, the logic change. It will choose
the best mode(fastest mode) which flash device and spi-nor host controller
both support.
qspi and fspi host controller do not support read 1-4-4 mode. so need to
set the tx to 1, let the common code finally select read 1-1-4 mode.

There are two type of i.MX8MM EVK board, one is populated with
LPDDR4(default dts), and one is populated with DDR4. these two
boards share most of the board design, but still have some difference.
imx8mm-evk has emmc support, imx8mm-ddr4-evk has gpmi nand support.
And also, the BT/WIFI module is different. So move the common dts
part into imx8mm-evk.dtsi for reuse.

Correct ldo1 voltage range from wrong high group(3.0V~3.3V) to low group
(1.6V~1.9V) because the ldo1 should be 1.8V. Actually, two voltage groups
have been supported at bd718x7-regulator driver, hence, just corrrect the
voltage range to 1.6V~3.3V. For ldo2@0.8V, correct voltage range too.
Otherwise, ldo1 would be kept @3.0V and ldo2@0.9V which violate i.mx8mm
datasheet as the below warning log in kernel:
[ 0.995524] LDO1: Bringing 1800000uV into 3000000-3000000uV
[ 0.999196] LDO2: Bringing 800000uV into 900000-900000uV

This is used by the imx-ddrc devfreq driver to implement dynamic
frequency scaling of DRAM.
Support for proactive scaling via interconnect will come later. The
high-performance bus masters which need that (display, vpu, gpu) are
mostly not yet enabled in upstream anyway.

The BUCK2 regulator is used for cpufreq voltage control, otherwise
configuration is mostly static.
This uses the newly-implemented rohm,reset-snvs-powered property to
properly handle the SNVS state of imx8mm.
Between BD71837 and BD71847 the BUCK3/4 regulators were removed but
datasheet and board schematics kept the names for BUCK5/6/7/8. The
driver however renumbered 5/6/7/8 to 3/4/5/6. Use the names from DT
bindings and add comments to signal this.
