video: sh_mobile_lcdcfb: Fix panning.
Fixed SH-Mobile panning. Previously the address of the frame to be displayed
was updated in the VSync end interrupt. This meant there was a minimum of 1
frame bewteen calling FBIOPAN_DISPLAY ioctl and the pan occuring. This meant
that apps were not able to use the FBIO_WAITFORVSYNC ioctl to wait for the
pan to complete. This patch moves the write to LDSA1R mirror reg into the
pan ioctl. Tested on MS7724 board against 2.6.33-rc7
