[v3 0/3] Break out as separate driver from boe-tv101wum-nl6 panel driver

[Cong Yang]

Linus series proposed to break out ili9882t as separate driver, 
but he didn't have time for that extensive rework of the driver.
As discussed by Linus and Doug [1], keep macro using the "struct panel_init_cmd"
until we get some resolution about the binary size issue.

In [v1 2/2], Doug suggested move the ili9882t_enter_sleep_mode function
to ili9882t_unprepare. I tried this scheme and the test failed, because
the touchpanel reset was already pulled low before the panel enter sleep,
which did not seem to meet the timing requirements. I hoped that the current
adding delay solution can be apply to solve the special requirements of this IC.
