The BOE TV101WUM-NL6 panel is mounted rotated 270 degrees in the
krane chassis (rotation property on the panel node in the upstream
DT). With the keyboard attached the tablet is used in landscape, so
set video rot=1 and enable CONFIG_CONSOLE_ROTATION: the uclass then
binds the rotated vidconsole1 driver, which writes glyphs rotated by
90 degrees clockwise into the native 1200x1920 portrait scanout and
uses the swapped console geometry (240 columns x 75 rows).
The framebuffer geometry and the depthcharge scanout path are
unchanged; only the console text placement rotates.
