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.
