drm/i915/bw: Initialize num_planes sensibly for the first plane group in TGL+

The way the TGL+ bw algorithm works is that 'num_planes'
is really a maximum number of allowed planes (whereas in
the ICL version it was more of a minimum), and the
assumption is that the first plane group (max[0]) can be
used with any number of planes (tgl_max_bw_index() always
returns 0 at the end).

To make things a bit less weird let's just set the first
plane group's num_planes to some big number to indicate it
has no real limit on the number of planes.
