Inculding below cleanup for BD71847 pmic driver:
--Remove ldo4 which's not used by board, otherwise,ldo4 will be on
since it's always_on.
--Remove buck5 which's not used by board too,although that may be off
by kernel requlator common framework after kernel bootup.
--Add dvs-run-voltage/dvs-idle-voltage setting for buck2 as i.mx8mm.

According to latest datasheet Rev.0.1, 03/2020, VDD_ARM does
NOT have dependency on VDD_SOC, so below table in datasheet
can be used directly for VDD_ARM:
Clock Voltage
1.2GHz 0.85V
1.4GHz 0.95V
1.5GHz 1.0V
For DDR4 EVK board, system runs at nominal mode, so GPU can
ONLY run up to 400MHz.
For LPDDR4 EVK board, system runs at over-drive mode, so GPU
can run up to 600MHz.

operating-points-v2 is used on i.MX8MN, so the 1.2GHz OPP overwrite
based on old i.MX8M cpu-freq driver is incorrect, correct it to be
based on operating-points-v2.

The 'attach-bridge' property for dsi port@1 can be used
to assit the dsim bridge to check if the port is used to
attach to the next bridge display device(e.g. adv7511).

After commit f7907e57ae ("regulator: fixed: add off-on-delay"), user
can use "off-on-delay-us" to define the regulator off-delay time.
For SD card, according to the spec requirement, for sd card power reset
operation, it need sd card supply voltage to be lower than 0.5v and keep
over 1ms, otherwise, next time power back the sd card supply voltage to
3.3v, sd card can't support SD3.0 mode again.
This patch add the off-on-delay-us to each board, make sure the sd power
reset behavior is align with the specification. Without this patch, when
do quick system suspend/resume test, some sd card can't work at SD3.0 mode
after system resume back.
