msm: camera: common: Add support for icc and switching bus scaling

Add support for disabling bus scaling by moving bus driver
references from cpas to cam utils. The references can be
switched based on compile time flags in defconfig. Also, add
interconnect support which has bw voting based on source and
destination bus IDs.
