Currently NVIDIA Tegra pin controller drivers cannot be compile tested,
unless ARCH_TEGRA is selected.  That partially defeats the purpose of
compile testing, since ARCH_TEGRA is pulled when building platform
kernels.  Solve it and allow compile testing independently of ARCH_TEGRA
choice which requires few less usual changes:

1. Descent in Makefile in to drivers/pinctrl/tegra/ unconditionally,
   because there is no menu option.

2. Depend on COMMON_CLK for PINCTRL_TEGRA20, because it uses
   clk_register_mux().

Not extensively compile tested yet. Pushing so LKP will pick it up. My
build tests are still in progress.

I tested all of Ubuntu cross compile environments - arm, arm64, i386,
x86_64, sparc, m68k, sh, s390, riscv and powerpc.
