media: ddbridge, cxd2099: include guard, fix unneeded NULL init, strings
Three really tiny minors in this single commit which all on their own
would just clutter up the commit history unnecessarily:
* ddbridge-regs.h is lacking an include guard. Add it.
* Fix an unnecessary NULL initialisation in ddbridge-ci. The declaration
of the ci struct ptr is immediately followed by kzalloc().
* Clarify that the CXD2099AR is a Sony device in the cxd2099 driver at a
few places including Kconfig.
