pinctrl: tegra: Consistently refer to SoC data

The SoC-specific data is stored in pmx->soc and that's used throughout
the driver to access this data. The probe function has access to a local
version of that copy and uses it in some occasions. Replace them with
the more standard pmx->soc access for more consistency.
