b40f734af9 Tegra114: Initialize System Counter (TSC) with osc frequency
T114 needs the SYSCTR0 counter initialized so the TSC can be
read by the kernel. Do it in the bootloader since it's a write-once
deal (secure/non-secure mode dependent).

8ca79b2ff4 Tegra30: Cardhu: Add pad config tables/code based on pinmux code
Pad config registers exist in APB_MISC_GP space, and control slew
rate, drive strengh, schmidt, high-speed, and low-power modes for
all of the pingroups in Tegra30. This builds off of the pinmux
way of constructing init tables to configure select pads (SDIOCFG,
for instance) during pinmux_init().

Currently, only SDIO1CFG is changed as per the TRM to work with
the SD-card slot on Cardhu.

Thanks to StephenW for the suggestion/original idea.

f29f086a09 Tegra: Move common clock code to arch/arm/cpu/tegra-common/clock.c
This 'commonizes' much of the clock/pll code. SoC-dependent code
and tables are left in arch/cpu/tegraXXX-common/clock.c

Some T30 tables needed whitespace fixes due to checkpatch complaints.
