arm64: dts: qcom: sm4250: add LPASS LPI pin controller

Browse Source 
Add the Low Power Audio SubSystem Low Power Island (LPASS LPI) pin
controller device node required for audio subsystem on Qualcomm
QRB4210 RB2. QRB4210 is based on sm4250 which has a slightly different
lpass pin controller comparing to sm6115.

While at this, also add description of lpi_i2s2 pins (active state)
required for audio playback via HDMI.
