Fixed code indent tabs in respective imx6qdl dtsi files and
also add space on imx6qdl-icore-rqs.dtsi on usdhc bus-width nodes.

All of the Gateworks Ventana boards based on the IMX6 SoC except for the
GW54xx use the LTC3676 PMIC. Add a device-tree node with interrupt support
for this PMIC. Additionally remove the simple-bus notation in the regulator
nodes and any fixed regulators that are provided by the PMIC.

bc677ff42e adds a device-tree property
to specify that an external watchdog reset is used to reset other
portions of the board and not just the IMX6 SoC.
This adds the property to the proper watchdog as well as the pinmux for
the Gateworks Ventana boards that use this external watchdog reset to
reset the PMIC which will reset all the PMIC power rails and not just
a chip-level IMX6 reset. This helps to work around various system issues
that can cause a hang when coming out of reset.

Ventana boards have an off-board connector with signals that can be pinmuxed
as either GPIO or PWM. This patch adds pwm device-tree nodes in the disabled
state which the bootloader can decide to enable based on bootloader config.

UHS-I support is available on Ventana boards with micro-SD sockets depending
on the board revision. To support this pinctl states for 100Mhz and 200MHz
must be added as well as pinmux of the VSELECT signal. In order to support
UHS-I the I/O rail of the 4-bit data bus must be switchable between 1.8V
and 3.3V.
By adding the no-1-8-v property, which disables UHS-I support, we allow the
bootloader to be in charge of selecting which boards have this capability
by removing that property if the board model/revision implement the support.
Additionally we will remove NANDF_CS1 here from the nand pinmux group as the
second chip-select is not used on any ventana boards and this is the pad
that is used for SD3_VELECT.
