We were already using the generic functions in our debugfs code, do the
same in jh057n_shutdown. This was suggested by Sam Ravnborg.

Most of them had these already but two mere missing. This eases
debugging.

This makes it symmetric with the panel init happening in enable().

If the panel is wrapped in a panel_bridge it gets prepar()ed before the
upstream DSI bridge which can cause hangs (e.g. with imx-nwl since clocks
are not enabled yet). To avoid this move the panel's first DSI access to
enable() so the upstream bridge can prepare the DSI host controller in
it's pre_enable().
This is also in line with other panel drivers.

Allow to specify regulators for vcc and iovcc. According to the data
sheet the panel wants vcc (2.8V) and iovcc (1.8V) and there's no startup
dependency between the two.

0xBF isn't in any ST7703 data sheet so mark it as unknown. This avoids
confusion on whether there is a missing command in that
dsi_generic_write_seq() call.

When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.

Support Rocktech jh057n00900 5.5" 720x1440 TFT LCD panel. It is a MIPI
DSI video mode panel.
The panel seems to use a Sitronix ST7703 look alike (most of the
commands look similar to the ST7703's data sheet but use a different
number of parameters). The initial version of the DSI init sequence
(including sleeps) were provided by the vendor. Sleeps were reduced
considerably though to speed up initialization.
