The CN10/CN11 on RZ/N1-EB board are headers to add jumpers to select which
CAN interface to route to the real CAN connector J16.

For a normal use case either we need to wire CAN1 or CAN2, but not both.

This patch enables CAN1 and disables CAN2 by default assuming CN10/CN11
is wired for CAN1.

With 'unevaluatedProperties' support implemented, there are a number of
warnings when running dtbs_check:

arch/arm64/boot/dts/renesas/r8a774b1-hihope-rzg2n-rev2-ex-idk-1110wr.dtb: spi@ee200000: Unevaluated properties are not allowed ('clock-names' was unexpected)
	From schema: Documentation/devicetree/bindings/memory-controllers/renesas,rpc-if.yaml

The main problem is that the DT bindings do not allow clock-names.
So just drop the clock-names properties from the SoC DTSI files.

The interrupt number for the HSCIF0 serial port, which serves as the
serial console on the White Hawk board, is incorrect, causing userspace
to hang immediately as soon as it tries to print something.
Kernel output is unaffected, as it is printed using polling.
