MLK-15316: ARM64: dts: fsl-imx8qxp-lpddr4-arm2-wm8962: enable WM8962 codec

Add DTS configuration for enabling WM8962 codec with iMX8QXP validation
board and the iMX8 debug board V2.

The connection in debug base board v2 is:
CODEC_PWR_EN:    SEAF_B_A18
CODEC_I2C_CLK:   SEAF_B_J32
CODEC_I2C_DAT:   SEAF_B_J31
AUD_MCLK:        SEAF_B_H24
AUD_TXC:         SEAF_B_B35
AUD_TXFS:        SEAF_B_B36
AUD_TXD:         SEAF_B_B37
AUD_RXD:         SEAF_B_A36
HEADPHONE_DET:   SEAF_B_A19
MICROPHONE_DET:  SEAF_B_A20
