arm64: dts: broadcom: Remove unused and undocumented nodes

The "silabs,si3226x" and "brcm,bdc-v0.16" nodes have no documentation
and no driver in the kernel, so remove them. They can be added back with
proper documentation if there is a need for them.

Note that if both USB ports have similar memory maps in relationship to
their USB PHY nodes, it looks like the device controller should have
been at 0x12000, not 0x21000?
