MAINTAINERS: Update Srivatsa S. Bhat's maintained areas

I have decided to change employers and I'm not sure if I'll be able to
spend as much time on the subsystems/drivers I maintain. So, I would
like to remove myself from the maintainer role.

Remove Srivatsa from the maintainers entry and add Ajay Kaher as an
additional reviewer/maintainer for the respective areas. Also, add an
entry to CREDITS for Srivatsa.

  [ bp: Merge all three into one patch, adjust commit message. ]
