drm/panthor: Reduce padding in gems debugfs for refcount

Browse Source 
The "gems" debugfs file is getting a little too wide for comfort. While
a lot of this is unavoidable due to the theoretical upper limits of
numbers here (e.g. size needs to be 16 chars because 2**48-1 in decimal
is 15 digits, plus one space for separation), the refcount column has a
decent 5 characters to be saved, as it can only ever contain a 10-digit
decimal number.

Reduce the refcount column's width to 11, which fulfils this requirement
with an additional space for separation.
