linux-handhelds-2.6 2.6.21-hh14: Add 2.6.21-hh14.

linux-handhelds-2.6 2.6.21-hh14: Add 2.6.21-hh14.
* Changes since -hh13 are:
1. gpiodev2 framework added, based on ideas of David Brownell's gpiolib
(i.e. there's still scalar namespace for GPIOs, and the code and data structures
for implicit dispatching to owning device; due to this, standard Genreic GPIO
API can be used intact). gpiolib itself was not used as it's not submitted for
mainline inclusion yet, so it's unclear in which shape it will go there at all.
2. gpiodev is deprecated in favor of gpiodev2.
3. asic3_base, htc-egpio: Add gpiodev2 support.
4. gpiodev_keys, asic3_keys are deprecated in favor of gpio_keys which now supports
keys on any kind of GPIO.
5. asic3_leds, hamcop_leds, samcop_leds are made child devices of the corresponding
SoC, their definitions merged to main machine file for many models.
6. pasic3-base.c: Driver for PASIC3 chip (htcmagician, htcblueangel, etc.).
7. leds-pasic3, ledtrig-backlight: New drivers.
8. h4000, h5000, htcmagician: Cleanup and more merging into main machine file.
