This patch adds support for the GiantPlus GPG48273QS5 4.3" WQVGA TFT LCD
panel to the simple-panel driver.

This panel is connected via a parallel bus and uses both HSYNC and
VSYNC, whose lengths are unfortunately not clearly defined. The
datasheet only specifies the front- and backporch length, but the timing
diagram suggests that both sync signals should be asserted for exactly
one clock cycle.

There are several different models of N116BGE. According to commit
0a2288c0 ("drm/panel: simple: Add Innolux N116BGE panel support"),
the video timings are for the eDP variant.

The clock and htotal values added by that patch are out of spec
according to the datasheets I have seen for the eDP N116BGE (-EA2 and
-EB2).

This patch changes the values to the "Typ" values on the datasheet.

The Hitachi TX23D38VM0CAA is a 9" WVGA TFT LCD panel and can be
supported by the simple-panel driver.

This panel is connected via LVDS and uses the data enable signal for

porches is arbitrary, as long as the complete horizontal blanking interval
is 256 clocks, and the vertical blanking interval is 45 lines.

Various panels were missing the .bpc field which encodes the number of
bits per color. Not every display driver relies on this value, but since
the panels can be used with any display engine it must be specified so
that if a driver knows how to differentiate based on this field it can
do so.

Add the new flags argument to calls of (devm_)gpiod_get*() and remove
any direction setting code afterwards.

Currently both forms (with or without the flags argument) are valid
thanks to transitional macros in <linux/gpio/consumer.h>. These macros
will be removed once all consumers are updated and the flags argument
will become compulsary.

simple-panel is not a valid panel model, so there is no data (video
timings, etc.) associated with it. Therefore drivers can't do anything
useful with it, so it should not appear in the table of OF matches.
