Alberto Panizzo aff5ce6ca8 drivers/video/backlight/l4f00242t03.c: fix reset sequence
The reset command is part of the init sequence and it take effect
only if the lcd is powered.

The effect of the bug was that the sequence:
set lcd power_state to FB_BLANK_POWERDOWN
set lcd power_state to FB_BLANK_UNBLANK
Did not produced a complete reboot of the LCD which was showing fuzzy
colours.

This was not experienced before implementing correctly all the LCD power
states with the patch [1].  Since before the patch [1] the regulators were
not touched and the LCD shutdown was reached with a register write.  After
the patch [1] a complete boot sequence with an initial reset is needed for
the display every time the LCD is powered up.
