From: Conor Dooley <conor.dooley@microchip.com>

The MSSPLL has 4 outputs, of which only the cpu/axi/ahb clock parent is
currently implemented.
Add the CAN clock too, as that'll be needed by the driver for the CAN
controller and uses output 3.
While we are here, the other two missing clocks, used by the eMMC/SD
controller and by the "user crypto".
