From: Christian Kellner <christ...@kellner.me>

Currently when dispatching hotkeys we check if the scancode is in
the range of 0 and TPACPI_HOTKEY_MAP_LEN, although the bottom 20
entries in the hotkey keymap are already adaptive keycodes.
Therefore we introduce a TP_ACPI_HOTKEYSCAN_ADAPTIVE_START and
ensure that we are in the range 0 and ADAPTIVE_START for the generic
keycode case.

Changes in v2:
- Don't initialize TP_ACPI_HOTKEYSCAN_ADAPTIVE_START manually, but use
  it to initialize TP_ACPI_HOTKEYSCAN_MUTE2
- Add a comment before the adaptive keycodes block
