s3c24xx: iPAQ rx1950 series

This patch series adds more support for iPAQ rx1950 PDA to linux:
1. LEDs driver -- it controls blue, green and red LEDs on rx1950
2. Battery driver -- adds ability to monitor and charge battery. This driver is suitable for H1940 PDA aswell (just need to write some machine specific callbacks and get voltage LUTs)

v2: removed ac registration from s3c_adc_battery driver, use pda_power instead for ac support

v3: split LEDs patch to driver and machine parts, split battery patch into battery + LED trigger parts, now battery driver can skip gpio/callbacks usage (if there's no gpio pin to determine that battery is full or if charger is enabled automatically)

v4: add .blink_set callback to LEDs driver instead of using LED_HALF value for blinking, remove LED triggers from battery driver completely (for now)

s3c-adc-battery is driver for monitoring
and charging battery on iPAQ H1930/H1940/RX1950.
It depends on s3c-adc driver to get battery voltage and current.
