backlight: add support for Pandora backlight
Add support for pandora (openpandora.org) backlight.
It might look like all this could be done using pwm_bl.c instead, but
there is a need of special programming sequence when turning on the LED
driver chip or else it will misbehave. Doing this using pwm_bl.c would
require to use some register programming and pwm functions from platform
code, and ARM maintainers are allergic to driver-like code in /arch/arm
nowadays. The PMIC PWM driver is currently missing too, so pwm_bl.c
can't be used anyway.
