qseecom: change bus scale up mode in resume function



The maximum bus bandwidth mode supported by bus bandwidth setting
function is 3 (i.e., HIGH), then to scale up bus bandwidth based on
cumulative mode may prevent us from updating the bus bandwidth
correctly when cumulative mode is greater than 3 (which is the case
if there are concurrent applications running). Thus, we made a
change to scale up bus bandwidth mode to at most 3 in qseecom
resume function.
