Fix FS#12243 : On 20GB H10, restore correct upside down state when waking LCD. 

In lcd_power_on(), R_DRV_OUTPUT_CONTROL and R_GATE_SCAN_START_POS are now
initialized like in lcd_set_flip(), so the display wakes up properly when it
is supposed to be upside down.

Thanks to Neil Sharrow for reporting the problem and testing the patch.
