From: Maxime Ripard <maxime at cerno.tech>
While the HVS has the same context memory size in the BCM2711 than in
the previous SoCs, the range allocated to the registers doubled and it
now takes 16k + 16k, compared to 8k + 16k before.
The KMS driver will use the whole context RAM though, eventually
resulting in a pointer dereference error when we access the higher half
of the context memory since it hasn't been mapped.
Fixes: 4564363351e2 ("ARM: dts: bcm2711: Enable the display pipeline")
