Make the following changes:

struct device * -> device_t
struct cfdata * -> cfdata_t
printf -> aprint_
device_t/softc split

Remove clause 3 and 4 from TNF licenses

Hide the bit invertion/shifting of values received from and send to the MCU
inside the j720ssp_readwrite function. This simplifies the calls to this
function a little.

Invert the brightness/contrast values so that higher values will
give more brightness/contrast instead of less.

No objection on port-hpcarm.

Split the Jornada 7xx drivers for the touch-panel, keyboard, lcd control
and power management into multiple files. This removes some dirty hacks
and improves the quality of the code.

- j720kbd.c

Split the Jornada 7xx drivers for the touch-panel, keyboard, lcd control
and power management into multiple files. This removes some dirty hacks
and improves the quality of the code.

- j720kbd.c - keyboard driver
* Converted to use the hpckbd(4) interface.
* Remove the old keymap file since it's no longer used.

- j720lcd.c - lcd brightness/control/power control

- j720pwr.c - power management
* Converted to use the hpcapm(4) interface.
* Fix the battery charge status. The values are non-linear so in order
to display a reasonable charge status we use a few charge points in
a table and interpolate between that.

- j720tp.c - touch-panel driver

- j720ssp.c - SSP port (on the SA-1110)

Many thanks to cube@ and uwe@ for providing useful feedback and reviewing
the changes.
