arm64: dts: realtek: Add EL2 virtual timer interrupt

Browse Source 
The ARMv8.2 based CPUs used in a number of Realtek SoCs are missing
the EL2 virtual timer interrupt. Add it.

Furthermore, the "kent" platform appears to assign PPI9 to both the
EL2 virtual timer and the GIC Maintenance Interrupt, which can't be
right. Attempt a fix by setting the former to PPI12, as PPI9 is
traditionally wired to the GIC itself.
