Subject: [PATCH] ARM: dts: broadcom: bcm2166x-common: Increase apps bus
 size to fit BCM21664 GIC

The BCM21664 GIC sits at a higher address than the apps bus currently
allows. This is because the apps bus was inherited from the BCM23550
DTSI, where the GIC sits at an earlier address in memory, and the DTSI
wasn't updated to match.

Increase the size of the apps bus to allow the BCM21664 GIC to work.

Fixes: a5d0d4a7bab5 ("ARM: dts: bcm-mobile: Split out nodes used by both BCM21664 and BCM23550")
