ARM: dts: bcm2711: Don't mark timer regs unconfigured

Source: Kernel.org
MR: 178873
Type: Integration
Disposition: Backport from git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable linux-5.10.y
ChangeID: 7ebb5928d1df7ecfb313893cdc7d91bee81d2910
Description:

[ Upstream commit c24f272 ]

During upstream process of Raspberry Pi 4 back in 2019 the ARMv7 stubs
didn't configured the ARM architectural timer. This firmware issue has
been fixed in 2020, which gave users enough time to update their system.

So drop this property to allow the use of the vDSO version of
clock_gettime.
