msm: clock-9625: Add IPA clock entry for bus driver

The Apps Bus driver needs to program the NOC registers at bootup for
several devices including IPA. Add the clock entry for IPA for bus
drivers to allow the system to boot otherwise it may result in a device
hang due to unclocked register access.
