media: venus: venc: Clamp param smaller than 1fps and bigger than 240
commit 417c01b92ec278a1118a05c6ad8a796eaa0c9c52 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 param if the user provides a value that will result in an invalid
fps.
