[ARM] pxa: add basic support for HP iPAQ hx4700 PDAs
This includes
- IrDA (pxafixp_ir),
- Buttons (gpio-keys),
- ASIC3 IRQ/GPIOs (asic3),
- EGPIOs (htc-egpio),
- ATI Imageon w3220 framebuffer (w100fb),
- Backlight (pwm-backlight),
- StrataFlash (physmap),
- Battery monitor (ds1wm,w1_ds2760,ds2760_battery)
- USB gadget support (pxa27x_udc,gpio_vbus).
- bq24022 battery charger (pda_power,bq24022)
- TSC2046 touchscreen (ads7846)
