wr_reg_wa() is not an appropriate name for a global function, and doesn't need
to be global anyway, so mark it static and avoid the warning:
drivers/video/fbdev/fsl-diu-fb.c:493:6: error: no previous prototype for 'wr_reg_wa' [-Werror=missing-prototypes]
Fixes: 0d9dab39fbbe ("powerpc/5121: fsl-diu-fb: fix issue with re-enabling DIU area descriptor")
