Add panel driver used in the OnePlus 6T.
No datasheet, based mostly on EDK2 init sequence and the downstream driver.
Note: This driver doesn't use previously mentioned "samsung,s6e3fc2x01"
by OnePlus 6T device-tree.
The reason is because DDIC itself without knowing the panel type used
with it will not give the driver enough information about the panel used,
as the panel cannot be autodetected.
While would be more practical to support the original compatible,
I would like to avoid it, to prevent confusing devs upstreaming DDICs.

This initial part of the panel driver was mostly generated by the
"linux-mdss-dsi-panel-driver-generator" tool [1], reading downstream
Android kernel file "dsi_panel_S6E88A0_AMS427AP24_qhd_octa_video.dtsi" [2].
On top of the generic output of the tool, there were a couple of changes
applied:
- Added mipi_dsi_dcs_set_display_on() to function s6e88a0_ams427ap24_on(),
otherwise the display does not show up.
- In functions s6e88a0_ams427ap24_on() and s6e88a0_ams427ap24_off()
changed DSI commands to multi context and used "accum_err" returns.
- In functions s6e88a0_ams427ap24_on() and s6e88a0_ams427ap24_off() replaced
msleep() by mipi_dsi_msleep().
- The function s6e88a0_ams427ap24_get_modes() was changed to make use of
drm_connector_helper_get_modes_fixed(). This also required to include
drm/drm_probe_helper.h.
- In function s6e88a0_ams427ap24_probe() registring the regulators was changed
to devm_regulator_bulk_get_const(). This required to change supplies in struct
s6e88a0_ams427ap24 to a pointer.
- Removed bool "prepared" from struct s6e88a0_ams427ap24 and according parts in
functions s6e88a0_ams427ap24_prepare() and s6e88a0_ams427ap24_unprepare().
- Removed include <linux/of.h>, it's not needed.
- Added comments to the mipi_dsi_dcs_write_seq_multi() lines in function
s6e88a0_ams427ap24_on().
