pinctrl: qcom: lpass-lpi: Remove unused member in struct lpi_pingroup

The group is not used anywhere, remove it. And if needed, it should be
struct pingroup anyway.

pinctrl: qcom: sm8650-lpass-lpi: add SM8650 LPASS

Add driver for the pin controller in Low Power Audio SubSystem (LPASS)
of Qualcomm SM8650 SoC.

Notable differences against SM8550 LPASS pin controller:
1. Additional address space for slew rate thus driver uses
LPI_FLAG_SLEW_RATE_SAME_REG and sets slew rate via different
register.

2. Two new pin mux functions: qca_swr_clk and qca_swr_data
