pinctrl: tegra: init Tegra20/30 at module_init time

The Tegra20/30 pinctrl drivers currently initializes at arch_initcall,
whereas Tegra114/124 pinctrl drivers initialize at module_init time.
Convert Tegra20/30 to work the same way as the other drivers.

pinctrl: tegra: dynamically calculate function list of groups

The per-SoC data structures for Tegra pinctrl stored some information
in a redundant way. Specifically, the list of groups that each function
could be muxed onto was stored once explicitly, and also as part of the
definition of each group. Eliminate this redundancy, and calculate each
function's list of valid groups at pinctrl probe time. This removes
thousands of lines of code from the pinctrl driver and ~16K from the
vmlinux binary size, and adds only about 500uS to the boot process (on
Tegra30; newer SoCs will likely be faster still).

pinctrl: tegra: consistency cleanup

Fix Tegra30/114/124 pinmux drivers consistency issues.
* Sort all lists of the same object type (e.g. #defines for pins, and
  the array that defines their names) in the same order.
* Whitespace fixes.
* Consistency in layout between the 3 drivers.

These driver files were also auto-generated, which should allow us to
make e.g. the U-Boot drivers completely consistent with the kernel in
the future:-)

genirq: define flag IRQ_SRC_DST_INVERTED, and accessors

Some devices have configurable IRQ output polarities. Software might
use IRQ_TYPE_* to determine how to configure such a device's IRQ
output polarity in order to match how the IRQ controller input is
configured. If the board or SoC inverts the signal between the
device's IRQ output and controller's IRQ output, software must be
aware of this fact, in order to program the IRQ output to the correct
(i.e. opposite) polarity. This flag provides that information.

dt: define IRQ flags bit 4 as src/dst inversion

Some devices have configurable IRQ output polarities. Software might
use IRQ specifier flag bits[3:0] to determine how to configure such a
device's IRQ output polarity in order to match how the IRQ controller
input is configured. If the board or SoC inverts the signal between the
device's IRQ output and controller's IRQ output, software must be
aware of this fact, in order to program the IRQ output to the correct
(i.e. opposite) polarity. This flag provides that information.

mfd: palmas: support IRQ inversion at the board level

Implement the new DT property ti,irq-externally-inverted, and add an
equivalent platform data field to match. This allows the driver to
correctly automatically configure the IRQ output polarity when the board
or SoC contains an inverter between the Palmas IRQ output and IRQ
controller input.

ARM: tegra: fix Dalmore PMIC IRQ polarity

The Tegra PMC's resume-from-sleep logic wants an active-low IRQ input
from the PMIC. However, the PMIC IRQ is also routed to the GIC, which
only supports active high IRQs (or rising edge). Hence, the signal must
be inverted in the PMC before being routed to the GIC. This implies that
the PMC DT property nvidia,invert-interrupt must be set, and it is.

The PMIC's DT interrupts property must represent the IRQ level at the
GIC, since that is the PMIC's parent IRQ controller. Fix the PMIC's
interrupts property to correctly describe the GIC input polarity.

However, the PMIC IRQ output's polarity is programmable in HW, and by
default follows the parent IRQ controller's input polarity. We need to
have an active-low output due to the inversion inside the Tegra PMC.
Hence, add the IRQ specifier flag which request that to the PMIC.
