pinctrl: tegra: dynamically calculate function list of groups
The per-SoC data structures for Tegra pinctrl stored some information in a redundant way. Specifically, the list of groups that each function could be muxed onto was stored once explicitly, and also as part of the definition of each group. Eliminate this redundancy, and calculate each function's list of valid groups at pinctrl probe time. This removes thousands of lines of code from the pinctrl driver and ~16K from the vmlinux binary size, and adds only about 500uS to the boot process (on Tegra30; newer SoCs will likely be faster still).
