pinctrl: qcom: sm8350-lpass-lpi: Merge with SC7280 to fix I2S2 and SWR TX pins



Qualcomm SC7280 and SM8350 SoCs have slightly different LPASS audio
blocks (v9.4.5 and v9.2), however the LPASS LPI pin controllers are
exactly the same.  The driver for SM8350 has two issues, which can be
fixed by simply moving over to SC7280 driver which has them correct:

1. "i2s2_data_groups" listed twice GPIO12, but should have both GPIO12
   and GPIO13,

2. "swr_tx_data_groups" contained GPIO5 for "swr_tx_data2" function, but
   that function is also available on GPIO14, thus listing it twice is
   not necessary.  OTOH, GPIO5 has also "swr_rx_data1", so selecting
   swr_rx_data function should not block  the TX one.
