ARM: OMAPFB: panel-sony-acx565akm: fix bad unlock balance
When booting Nokia N900 smartphone with v3.12 + omap2plus_defconfig
(LOCKDEP enabled) and CONFIG_DISPLAY_PANEL_SONY_ACX565AKM enabled,
the following BUG is seen during the boot:
[ 7.302154] =====================================
[ 7.307128] [ BUG: bad unlock balance detected! ]
[ 7.312103] 3.12.0-los.git-2093492-00120-g5e01dc7 #3 Not tainted
[ 7.318450] -------------------------------------
[ 7.323425] kworker/u2:1/12 is trying to release lock (&ddata->mutex) at:
[ 7.330657] [<c031b760>] acx565akm_enable+0x12c/0x18c
[ 7.335998] but there are no more locks to release!
Fix by removing double unlock and handling the locking completely inside
acx565akm_panel_power_on() when doing the power on.
