Switch the hotkey keymap handling over to the sparse-keymap helpers,
there should be no functional changes from this.
Note all the mappings to KEY_UNKNOWN are removed since that is the default
behavior of sparse_keymap_report_event() for unknown scancodes.
Also drop the big comment about making changes to the keymaps since
the contents of that comment are mostly obsolete.

- * the various ThinkPad models. The driver behaves
- * differently for KEY_RESERVED: such keys have their
- * hot key mask *unset* in mask_recommended, and also
- * in the initial hot key mask programmed into the
- * firmware at driver load time, which means the firm-
- * ware may react very differently if you change them to
- * something else;
- *
- * 2. You must be subscribed to the linux-thinkpad and
- * ibm-acpi-devel mailing lists, and you should read the
- * list archives since 2007 if you want to change the
- * keymaps. This requirement exists so that you will
- * know the past history of problems with the thinkpad-
- * acpi driver keymaps, and also that you will be
- * listening to any bug reports;
- *
- * 3. Do not send thinkpad-acpi specific patches directly to
- * for merging, *ever*. Send them to the linux-acpi
- * mailinglist for comments. Merging is to be done only
- * through acpi-test and the ACPI maintainer.
- *
- * If the above is too much to ask, don't change the keymap.
- * Ask the thinkpad-acpi maintainer to do it, instead.
