video: ssd1307fb: Handle width and height that are not multiple of 8
Some displays have dimensions that are not multiple of eight, for example
height of 36, but the driver divided the dimensions by 8. Defining display
to the next multiple of 8 is not good as then the display registers get
configured to dimensions that do not match. This contradicts intructions
by some display manufacturers.
Use DIV_ROUND_UP to multiple of 8 when needed so correct values can be
used.
The ssd1307fb_update_display bit reordering receives a simplification in
the process.
