At least the table in pinmux.c:tegra_soc_pingroups matches the kernel's
list of pins in terms of pin name and register offsets. I didn't check
any other aspect of the changes, but the changes are conceptually fine
by me.

It might be nice to validate the entire of the pinmux driver tables and
Dalmore configuration against the kernel's
drivers/pinctrl/pinctrl-tegra114.c (and
arch/arm/boot/dts/tegra114-dalmore.dts once pinctrl nodes are added
there) some time.

FYI, the JTAG_RTCK entry that already exists here isn't in the kernel's
driver. That could be simply an oversight in the kernel driver though.

Nit: 0x3338c should be 0x338c.
