This is used to specify the page start address offset of the display RAM.
The value is used as offset when setting the page start address with the
SSD130X_SET_PAGE_RANGE command, and the driver currently sets its value to
1 if the property is not present in the Device Tree.
But the datasheet mentions that the value on reset for the page start is a
0, so it makes more sense to also have 0 as the default value for the page
offset if the property is not present.
In fact, using a default value of 1 leads to the display not working when
the fbdev is attached to the framebuffer console.
