FS#5712 - X5 Backlight Brightness Improvement/Fix
Improves the backlight brightness setting interface/parameters for the iAudio X5.
Parameters held to acceptable ranges per D305A datasheet:
* PWM frequency reduced to 512Hz to keep within 400-2000Hz range (doesn't hurt brightness).
* PWM duty cycle kept within 15%-100% range.
Higher value now equals brighter display by inverting GPO1 on the PMU. This was reversed before.
Improvements to the set_backlight_brightness function.
Default brightness now the same as the boot setting.

I reviewed it and it seems OK, but I can't test low-level stuff without an actual device.
Gimme one positive user report (except yours) and it's in :)
Should I grovel for one on IRC? hehe :D
I should warn that it would break your LCD flash patch because of the PMU change since LCD OFF is now 0x80 instead of 0x70.
BTW: How'd you test the backlight thing if you don't have a device?
Actually, on second thought, it wouldn't really break it or vice versa. Off is simply off as done in pcf50606-x.c.
