touch_noise_filter: Remove default value for BASE_VER
BASE_VER must match the recent version of libchrome being used.
Having it set to a dummy default version that doesn't match the revision
number of libchrome doesn't help anyone much.
Removed the default value and added an error message instructing
the user to set BASE_VER to correct revision number if not already
set (which is the case in normal builds, where BASE_VER comes from
libchrome.eclass).
