[V4 i-g-t 0/3] Skip if current & requested BPC doesn't match

[Bhanuprakash Modem]

The "max bpc" property only ensures that the bpc will not go beyond
the value set through this property. It does not guarantee that the
same bpc will be used for the given mode.

If clock/bandwidth constraints permit, the max bpc will be used to
show the mode, otherwise the bpc will be reduced. So, if we really
want a particular bpc set, we can try reducing the resolution, till
we get the bpc that we set in max bpc property.

So, skip the test, if there is no valid resolution to get the same
bpc as set by max_bpc property.
