ARM: tegra: pinctrl: remove duplication
Much of arch/arm/cpu/tegra*-common/pinmux.c is identical. Remove the duplication by creating pinmux-common.c for all the identical code. This leaves: * arch/arm/include/asm/arch-tegra*/pinmux.h defining only the names of the various pins/pin groups, drive groups, and mux functions. * arch/arm/cpu/tegra*-common/pinmux.c containing only the lookup table stating which pin groups support which mux functions. The code in pinmux-common.c is semantically identical to that in the various original pinmux.c, but had some consistency and cleanup fixes applied during migration. I removed the definition of struct pmux_tri_ctlr, since this is different between SoCs (especially Tegra20 vs all others), and it's much simpler to deal with this via the new REG/MUX_REG/... defines. spl.c, warmboot.c, and warmboot_avp.c needed updates due to this, since they previously hijacked this struct to encode the location of some non-pinmux registers. Now, that code simply calculates these register addresses directly using simple and obvious math. I like this method better irrespective of the pinmux code cleanup anyway.
