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.
