ASoC: dt-bindings: Correct interrupt flags in examples
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 some
logical behavior behind the name "ACTIVE_xxx", this is:
  ACTIVE_HIGH => IRQ_TYPE_LEVEL_HIGH

Anatol Pomozov cdab0d4ecc ASoC: rt5677: use 'active low' logic for reset pin
According to the datasheet RESET is active low pin, i.e. system goes to
reset state when pin signal is low.

The previous implementeation was assuming the pin is configured as
'active high' in DTS. Changle the gpio handling code and DTS configuration
to 'active low'.

Anatol Pomozov f9f6a592cf ASoC: rt5677: Add a configuration option for LDO2_POW pin
Some boards have this pin statically tied and do not require any configuration,
some other boards allow to enable chip using GPIO.

Add an option that tells which GPIO is used to power the audio codec.
