media: venus: vdec: Clamp param smaller than 1fps and bigger than 240.
commit 377dc500d253f0b26732b2cb062e89668aef890a upstream.
The driver uses "whole" fps in all its calculations (e.g. in
load_per_instance()). Those calculation expect an fps bigger than 1, and
not big enough to overflow.
Clamp the value if the user provides a param that will result in an invalid
fps.
