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.

Currently it is not possible to have HDMI and LVDS working simultaneously,
because both ports try to use PLL5.

Move the LVDS clock parent to PLL3_USB_OTG, so that HDMI and LVDS can be
driven from independent sources.

With this change the LDB pixel clock goes to 68.57 MHz, which is still
within the valid range for the displays supported by the Ventana boards.

Gateworks Ventana boards seem to need "RGMII-ID" (internal delay)
PHY mode, instead of simple "RGMII", for their Marvell 88E1510
transceiver. Otherwise, the Ethernet MAC doesn't work with Marvell PHY
driver (TX doesn't seem to work correctly).

Tested on GW5400 rev. C.

This bug affects ARM Fedora 23.

cd-gpios polarity should be changed to GPIO_ACTIVE_LOW and wp-gpios
should be changed to GPIO_ACTIVE_HIGH.
Otherwise, the SD may not work properly due to wrong polarity inversion
specified in DT after switch to common parsing function mmc_of_parse().

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.

imx6qdl-gw5x boards use sgtl5000 codec and the machine file (imx-sgtl5000)
already sets SSI in slave mode and codec in master mode, so there is no need
for having this property.

 - grouping pinctrl in logical alphabatized groups
 - remove any pinctrl not being used by a driver or needed by user
 - move iomuxc to bottom of file for readability

The DAI mode is and should be configured by the sound card driver as
codec and ssi have to be in the right modes to communicate with each
other. It is possible to operate the ssi unit or the codec in master mode,
sometimes even on the same board in different configurations.

With the latest changes in the fsl-ssi driver, the 'fsl,mode' property
is only handled as a fallback property. If the sound card sets the DAI
mode correctly, this fallback configuration is dropped.
