Subject: [PATCH 4/6] staging: sm750fb: Expose hw712_fillrect externally

This patch adds a reference to hw712_fillrect which is not used elsewhere in the driver,
but appears to be an alternative to the hw_fillrect method. This patch fixes the following sparse warning:-

drivers/staging/sm750fb/sm750_accel.c:95:5: warning: symbol 'hw712_fillrect' was not declared. Should it be static?
