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

RT5659/RT5658 audio CODEC
This device supports I2C only.
Required properties:
- compatible : One of "realtek,rt5659" or "realtek,rt5658".
- reg : The I2C address of the device.
- interrupts : The CODEC's interrupt output.
Optional properties:
- clocks: The phandle of the master clock to the CODEC
- clock-names: Should be "mclk"
- realtek,in1-differential
- realtek,in3-differential
- realtek,in4-differential
Boolean. Indicate MIC1/3/4 input are differential, rather than single-ended.
- realtek,dmic1-data-pin
0: dmic1 is not used
1: using IN2N pin as dmic1 data pin
2: using GPIO5 pin as dmic1 data pin
3: using GPIO9 pin as dmic1 data pin
4: using GPIO11 pin as dmic1 data pin
- realtek,dmic2-data-pin
0: dmic2 is not used
1: using IN2P pin as dmic2 data pin
2: using GPIO6 pin as dmic2 data pin
3: using GPIO10 pin as dmic2 data pin
4: using GPIO12 pin as dmic2 data pin
- realtek,jd-src
0: No JD is used
1: using JD3 as JD source
- realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin.
- realtek,reset-gpios : The GPIO that controls the CODEC's RESET pin.
