The sta_himax83102 panel sometimes shows abnormally flickering
horizontal lines. The front gate output will precharge the X point of
the next pole circuit before TP term starts, and wait until the end of
the TP term to resume the CLK. For this reason, the X point must be
maintained during the TP term. In abnormal case, we measured a slight
leakage at point X. This is because during the TP term, the GPW does not
fully pull the VGL low, causing the TFT to not be closed tightly.
To fix this, we completely pull GPW to VGL before entering the TP term.
This will ensure that the TFT is closed tightly and prevent the abnormal
display.

In the datasheet of ILI9882T [1] section 3.11 Power On/Off Sequence,
the TReset-CMD (Reset to First Command in Display Sleep In Mode) should
be larger than 10ms, but it's 1.1ms now. This may cause abnormal
display as some commands may be lost during power on. Fix this and
leave some margins by increasing TReset-CMD to 20ms. Also, to align
with the kernel driver structure starry_ili9882t_init_cmd, add 20ms
delay at the end of command.

There is a problem of screen shake on the old panel[1]. So increase the
panel GOP component pull-down circuit size in hardware, and update the
initialization code at the same time. The new initialization code is
mainly adjusted for GOP timing. When Display sleep in, raise all GOP
signals to VGHO and then drop to GND. In order to be consistent with
the current panel model, let's rename this file.
[1]: INX old panel product number is HJ110IZ-01A-B1, and the new
panel product number is HJ110IZ-01A-B2. We have recalled the shipment
old panel.

coreboot logs the error below, since the value of hporch is too small. Increasing hbl from 80 to 174, and hso from 40 to 72 to revise the HBP(Horizontal Back Porch) and HFP(Horizontal Front Porch). After revising this, the actual measurement frame rate is 60.1Hz.
[ERROR]HFP plus HBP is not greater than d_phy, the panel may not work

cb_err_t was meant to be used in place of `enum cb_err` in all
situations, but the choice to use a typedef here seems to be
controversial. We should not be arbitrarily using two different
identifiers for the same thing across the codebase, so since there are
no use cases for serializing enum cb_err at the moment (which would be
the primary reason to typedef a fixed-width integer instead), remove
cb_err_t again for now.

Our MIPI panel initialization framework differentiates between DCS and
GENERIC commands, but the exact interpretation of those terms is left to
the platform drivers. In practice, the MIPI DSI transaction codes for
these are standardized and platforms always need to do the same
operation of combining the command length and transfer type into a
correct DSI protocol code. This patch factors out the various
platform-specific DSI protocol definitions into a single global one and
moves the transaction type calculation into the common panel framework.
The Qualcomm SC7180 implementation which previously only supported DCS
commands is enhanced to (hopefully? untested for now...) also support
GENERIC commands. While we're rewriting that whole section also fix some
other issues about how exactly long and short commands need to be passed
to that hardware which we identified in the meantime.

It doesn't make sense to store the orientation field directly in the
panel information structure, which is supposed to be reuseable between
different boards. The thing that determines orientation is how that
panel is built into the board in question, which only the board itself
can know. The same portrait panel could be rotated left to be used as
landscape in one board and rotated right to be used as landscape in
another. This patch moves the orientation field out of the panel
structure back into the mainboards to reflect this.
