The Documentation/devicetree/bindings/opp/opp-v2-base.yaml expects the OPP

Only the i.MX8M DTs are affected per "git grep 'opp-[0-9]\+M'", so fix them.

arm64: dts: imx8mm: Correct WDOG_B pin configuration

Different revision of i.MX8MM EVK boards may have different external
pull up registor design, some are enabled while some are NOT, to make
sure the WDOG_B pin works properly, better to enable internal pull up
resistor. Since enabling internal pull up resistor is NOT harmful and
having benefit of flexibility on different board design, just enable
it for all i.MX8MM boards; And schmitt input is NOT necessary for this
WDOG_B output pin, so remove it; Open drain outputs provide more
flexibility to a designer as they can be pulled-up to any voltage found
in the system, so enable it as well.

arm64: dts: imx8mm: correct interrupt flags

GPIO_ACTIVE_x flags are not correct in the context of interrupt flags.
These are simple defines so they could be used in DTS but they will not
have the same meaning:
1. GPIO_ACTIVE_HIGH = 0 = IRQ_TYPE_NONE
2. GPIO_ACTIVE_LOW = 1 = IRQ_TYPE_EDGE_RISING

Correct the interrupt flags, assuming the author of the code wanted same
logical behavior behind the name "ACTIVE_xxx", this is:
ACTIVE_LOW => IRQ_TYPE_LEVEL_LOW
ACTIVE_HIGH => IRQ_TYPE_LEVEL_HIGH

In case of level low interrupts, enable also internal pull up. It is
required at least on imx8mm-evk, according to schematics.

The schematics for Variscite imx8mm-var-som are not available and
I was unable to get proper configuration from Variscite.
