dt-bindings: clock: anlogic,dr1v90-cru: make external clocks optional
The main oscillator is the only required input clock for the CRU, while
the external CAN and WDT clocks are optional board-level inputs. The
binding currently requires all three clocks, forcing device trees for
boards without these external inputs to add stub fixed-clock nodes for
which no meaningful clock-frequency can be specified.
Allow the clocks and clock-names properties to contain just "osc",
optionally followed by either or both of "can_ext" and "wdt_ext".
