It turns out that I had misconfigured the device I was using the panel
with; the bus data polarity is not high for this panel, I had to change
the config on the display controller's side.
Fix the panel config to properly reflect its accurate settings.

After more investigation, I've found that it's not the panel driver
config that needs to be modified to invert the data polarity, but
the FIMD config.
Add the missing invert-vclk option that is required to get the display
to work correctly.
