From: Oliver Graute <oliver.graute@kococonnector.com>
commit b6821b0d9b56386d2bf14806f90ec401468c799f upstream.
In rare cases the display is flipped or mirrored. This was observed more
often in a low temperature environment. A clean reset on init_display()
should help to get registers in a sane state.
Fixes: ef8f317795da (staging: fbtft: use init function instead of init sequence)
