B4 and B3 board
For imx8mq-evk board, B4 board change touch/mipi-hdmi connected i2c bus from i2c1 to i2c3.
So this patch make the touch and mipi-hdmi work for both B4 and B3 board.

Currently, there are a lot of dts bindings duplicated into many files
because of the multiple possible use-cases.
Still, some bindings can be defined in a single file, then re-used in
each specific dts file, with the required specific scenario changes.
Therefore:
1. Move the adv7535 (DSI-HDMI converter) and synaptics_dsx_ts (DSI touch)
definitions to fsl-imx8mq-evk.dts file.
2. Removed the max-res binding from the main dtsi file. This is a
limitation and should NOT be present in the main definition of lcdif.
Use this limitation only in specific dts files which requires such
limitations. For example in the dual-display.dts file, where the lcdif
is used along with the dcss; lcdif has to be limited because of the low
bandwidth when used in the same time with dcss.

Add dts bindings for the adv7535 i2c interrupts on imx8mq. These
interrupts are used to catch the HPD event from HDMI sink.
Also, rise the max-res of the lcdif to 1920x1080, when used as
standalone. Since the DCSS is turned off on this dts file, the LCDIF can
be used at full-hd resolution.

Since the ADV7535 address for DSI-CEC can be configured from DTS file,
update the ADV7535 specific files in order to remove the disabling
camera node and update the ADV7535 node to use a different i2c address.
Currently 0x3c was used, conflicting with camera. Now, program ADV7535
to use 0x3b for the DSI-CEC memory map.

To allow the PLL to become stable before enabling the clocks, we may
need a delay. This patch adds a new property to specify this delay from
DTS file.

For some reasons, the sync polarity of the eLCDIF when used with NWL DSI
controller needs to be HIGH, so set it in the DTS nodes.

Since the display subsystem is using DRM framework by
default, it is unnecessary to keep '_drm' postfix in
the device node names anymore to indicate that they
are DRM devices.

The MIPI-DSI nodes related to ADV7535 are in conflict with OV5640
MIPI-CSI camera, since they share the same address on the same i2c bus:
0x3c. In order to make DSI work with ADV7535 adapter, the OV5640 camera
needs to be disabled.
Also, for LCDIF (MXSFB), the irqsteer_dcss module needs to be disabled,
otherwise it will interfere in the suspend/resume routines.
