dts: bcm2711: Don't mark timer regs unconfigured
Browse files Browse the repository at this point in the history
The DT property arm,cpu-registers-not-fw-configured tells the kernel
that the ARM architectural timer has not been configured by the
firmware. This prevents the use of a vDSO - a faster alternative to a
syscall for some common kernel operations.

However, on Pi 4 the firmware does configure the timer, so this property
is unnecessary. Delete it.
