This adds freefall handling to hp_accel driver. According to HP, it
should just work, without us having to set the chip up by hand.
hpfall.c is example .c program that parks the disk when accelerometer
detects free fall. It should work; for now, it uses fixed 20seconds
protection period.

According to dmesg my laptop model HP 6510b is not being recognized by this
driver. After I have modified "lis3lv02d.c" axes in Neverball are OK.

The LED on HP notebooks is connected through ACPI. That unfortunately
means that it needs to be delayed by using schedule_work() to avoid
calling the ACPI interpreter from an invalid context.
[akpm@linux-foundation.org: use flush_work() rather than sort-of reimplementing it]

Move the second part of the HP laptop disk protection functionality (a red
led) to the same driver. From a purely Linux developer's point of view,
the led and the accelerometer have nothing related. However, they
correspond to the same ACPI functionality, and so will always be used
together, moreover as they share the same ACPI PNP alias, there is no
other simple to allow to have same loaded at the same time if they are not
in the same module. Also make it requires the led class to compile and
update the Kconfig text.

The sensor can be accessed via various buses. In particular, SPI, I²C
and, on HP laptops, via a specific ACPI API (the only one currently
supported). Separate this latest platform from the core of the sensor
driver to allow support for the other bus type. The second, and more
direct goal is actually to be able to merge this part with the
hp-disk-leds driver, which has the same ACPI PNP number.
