The Starry ILI9882t-based panel should never have been part of the boe tv101wum driver, it is clearly based on the Ilitek ILI9882t display controller and if you look at the custom command sequences for the panel these clearly contain the signature Ilitek page switch (0xff) commands. The hardware has nothing in common with the other panels supported by this driver.
Break this out into a separate driver and config symbol instead. If the placement here is out of convenience for using similar code, we should consider creating a helper library instead.
