This renames all the pinmux pins, drive groups, and functions so they
have a prefix which matches the type name. These lists are also auto-
generated using scripts that were also used to generate the kernel
pinctrl drivers. This ensures that the lists are consistent between the
two.
The entries in tegra114_pingroups[] are all updated to remove the columns
which are no longer used.
All affected code is updated to match.
This introduces a few changes to pin/group/function naming and the set of
available functions for each pin. The new values now exactly match the
TRM; the chip documentation. I adjusted a few entries in
pinmux-config-dalmore.h due to this.

Clean up the naming of pinmux-related objects:
* Refer to drive groups rather than pad groups to match the Linux kernel.
* Ensure all pinmux API types are prefixed with pmux_, values (defines)
are prefixed with PMUX_, and functions prefixed with pinmux_.
* Modify a few type names to make their content clearer.
* Minimal changes to SoC-specific .h/.c files are made so the code still
compiles. A separate per-SoC change will be made immediately following,
in order to keep individual patch size down.

I2C protocol requires open-drain IOs. Fix the Dalmore and Venice2 pinmux
tables to configure the IOs correctly. Without this, Tegra may actively
drive the lines high while an external device is actively driving the
lines low, which can only lead to bad things.

SDIO1 (the SD-card slot on Dalmore) needs to have its pads setup
before the MMC driver is added.

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, no padcfg entries exist. SDIO3CFG will be added when the
MMC driver is added as per the TRM to work with the SD-card slot on
Dalmore E1611.

The pinmux code issues a warning if the caller attempts to disable the
lock bit in a pinmux register, since this is impossible (once it's
locked, the only way to unlock it is to reset the device/pmt controller).
The I2C/DDC/CEC/USB macros expect a lock setting to be passed in,
and the previous setting of DISABLE caused the pinmux table parsing
code to issue the warning. Changing the lock bits in these table
entries to DEFAULT (i.e. don't touch it) fixes this.

Use the latest tables & code from our internal U-Boot repo.
The SDMMC3_CD, CLK_LB_IN and CLK_LB_OUT offsets in the pingroup
table were off by a few indices, causing the pinmux init code to
write bad data to the PINMUX_AUX_ regs. This also enabled the lock
bit, which made it impossible to reconfig the pads correctly for
SDMMC3 (SD card on Dalmore) operation. Also fixes SPI_CS2_N,
USB_VBUS_EN0, HDMI_CEC and UART2_RXD/TXD muxes.

This build is stripped down. It boots to the command prompt.
GPIO is the only peripheral supported. Others TBD.
