quirks: AddHP Spectre x360 15 ModelTabletModeNoSuspend keyboard quirk

The HP stream x360's embedded-controller filters out events form its
builtin keyboard when in tablet-mode itself; and it has a volume up/down
on the side.

Do not suspend the keyboard when in tablet-mode so that the volume
up/down button keeps working when in tablet-mode.

Add a ModelTabletModeNoSuspend quirk so that the home button keeps
working when in tablet-mode.
This can safely be done since the rest of the keyboard gets disabled by
the embedded-controller for us.
