pinctrl: qcom: sm8450-lpass-lpi: correct swr_rx_data group

commit 5921b250 upstream.

According to hardware programming guide, the swr_rx_data pin group has
only two pins (GPIO5 and GPIO6).  This is also visible in "struct
sm8450_groups" in the driver - GPIO15 does not have swr_rx_data
function.

Fixes: ec1652fc
