ARM: shmobile: r8a7778: Update DTS to include CPU frequency

From: Magnus Damm <[email protected]>

Add CPU Frequency information to the r8a7778 DTS file. This will allow us to use the shared C code on r8a7778 and BockW which reads out the clock frequency from DT and calculates the delay settings from there.

Also add other missing CPU information to the r8a7778 DTS.
