arm64: dts: broadcom: bcm2712: Remove non-functional EL2 virtual timer
Commit d87773de9efe1 ("clocksource/drivers/arm_arch_timer: Default to EL2
virtual timer when running VHE") causes boot to hang on Raspberry Pi 5.
The newly-selected EL2 virtual timer does not generate any interrupts,
even though the GIC_DIST_ENABLE_SET flag has been confirmed set via
readback.
It is highly unusual that this timer interrupt is non-operational because
this is a standard GIC interrupt corresponding to a standard Cortex-A76
CPU timer. However, Broadcom have confirmed for this SoC:
> the interrupt line was never connected in the first place as this was
> not identified as being a requirement
Remove the corresponding DeviceTree entry.
