[PATCH] pinctrl: tegra264: fix DAP2 DIN/DOUT mux functions

[Prathamesh Shete <pshete@nvidia.com>]

The dap2_din_pv7 and dap2_dout_pw0 pin groups were assigned swapped
primary mux functions: dap2_din_pv7 (data input) was muxed to
I2S2_SDATA_OUT and dap2_dout_pw0 (data output) to I2S2_SDATA_IN. As a
result the I2S2 data-in and data-out signals were routed to the wrong
pins, breaking DAP2 audio.

Correct the functions so dap2_din_pv7 uses I2S2_SDATA_IN and dap2_dout_pw0
uses I2S2_SDATA_OUT. The register offsets and drive-group macros are
already correct and are left unchanged.
