ACPI: thinkpad-acpi: change thinkpad-acpi input default and kconfig help

Browse Source 
The current kconfig help text was misleading users.  Also, the default for
an input-layer-optimized support caused way too many problems without
up-to-date userspace in place.

So, rework the help text, and change the default to N.  Note that
distributions are supposed to enable this option as soon as they update HAL
to a version that handles the thinkpad-acpi new input layer interface.

---help---
Enables hot key handling over the input layer by default. If unset,
the driver does not enable any hot key handling by default, and also
starts up with a mostly empty keymap.
This option enables thinkpad-acpi hot key handling over the input
layer at driver load time. When it is unset, the driver does not
enable hot key handling by default, and also starts up with a mostly
empty keymap.
If you are not sure, say Y here. Say N to retain the deprecated
behavior of ibm-acpi, and thinkpad-acpi for kernels up to 2.6.21.
This option should be enabled if you have a new enough HAL or other
userspace support that properly handles the thinkpad-acpi event
device. It auto-tunes the hot key support to those reported by the
firmware and enables it automatically.
If unsure, say N here to retain the old behaviour of ibm-acpi, and
thinkpad-acpi up to kernel 2.6.21: userspace will have to enable and
set up the thinkpad-acpi hot key handling using the sysfs interace
after loading the driver.
