msm: Pull RTB out of the board file

The RTB device belongs in the devices file with the rest of devices.
Pull RTB out of the board file and add definitons in appropriate
header files to allow access to parts in the board file. Also
remove CONFIG_MSM_RTB definitions around devices and functions since
the driver matching does the appropriate thing if CONFIG_MSM_RTB isn't
there.
