Geert Uytterhoeven Nov. 29, 2018, 10:50 a.m. UTC 
The R-Car Gen3 HardWare Manual Errata for Rev. 0.80 (Feb 28, 2018) added
the CPEX clock on R-Car D3.  This clock can be selected as a clock
source for CMT1 (Compare Match Timer Type 1).

Add the missing clock to the DT bindings header, and implement support
for it in the clock driver.
