drivers/mipi: Modify INX_P110ZZD_DF0 panel initialization code
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.
