Disable PL011 clock migration for machine types before
virt-rhel8.4.0.

The regression was introduced by aac63e0e6ea3
("hw/char/pl011: add a clock input"), in 8.4,
causing failure of migration between qemu 8.4 towards
older ones.

The fix was taken in 8.5 as part of the rebase,
e6fa978d8343 ("hw/arm/virt: Disable pl011 clock migration
if needed"). But the compat needs to be applied in
hw_compat_rhel_8_3[].
