drivers/video: fsl-diu-fb: remove broken reference count enabling the display
The functions enable_lcdc() and disable_lcdc() used the variable fb_enable
to keep a reference count of when the display is enabled, but the code is
broken. The display is always disabled when disable_lcdc(), and it is
always enabled when enable_lcdc() is called, regardless of the value of
fb_enable. Obviously, we don't need to keep a reference count, so just
remove the variable.
