[PATCH v1] fbtft: fb_st7789v: added reset on init_display()

[Oliver Graute]

staging: fbtft: fb_st7789v: reset display before initialization

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.
