[PATCH 6.1.y-cip 1/2] of: Change of_machine_is_compatible() to return bool

From: Michael Ellerman <[email protected]>

commit cefdb366dcbe97908b6055595a15bf7689556bf8 upstream.

of_machine_is_compatible() currently returns a positive integer if it
finds a match. However none of the callers ever check the value, they
all treat it as a true/false.

So change of_machine_is_compatible() to return bool, which will allow
the implementation to be changed in a subsequent patch.
