soc/qualcomm/ipq40xx: Remove unnecessary allocation
The bus variable doesn't live outside the scope of this function, and is
only used as a convenient way for passing the pointers to all the
sub-functions, so it doesn't need to be allocated. Put it on the stack
instead. A similar fix for ipq806x was done in
0f33d8c29a
(soc/qualcomm/ipq806x: Remove unnecessary allocation).
