 msm: msm_bus: Fix the type error causing bandwidth overflow

On legacy chipsets, long int was being used to store
return value after calculating interleaved bw. However,
NoCs support 64-bit integers ab/ib values. problme occurs
if client request for higher bw and if difference of ab
value exceeds the range of 32 bit integer, the Value
overflows and turns negative, which leads to wrong bw calculation.

This patch fixes this integer overflow by correcting argument
type to store bw.

 msm: msm_bus: send correct value to bw division function

While calculating bw for existing client request
sometimes it can go to negative if client unregisters
or send request with lesser ab/ib values. Bus driver
will divide bandwidth if interleaving enabled.

Added a macro wrapper to handle negative bw values
since the division utility function can't handle
negative values
