Merge tag 'vexpress-updates-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/dt

ARMv7 Vexpress updates for v5.3

1. Couple of updates switching to use new/updated bindings for CoreSight
   dynamic funnel components and NOR flash partition type
2. Disable NOR flash on Vexpress TC2 platform as it conflicts with CPU
   power management. This follows what we have on ARMv8 Juno platform
   and is required after recent commit that enabled CFI NOR FLASH in
   multi_v7 defconfig

* tag 'vexpress-updates-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux:
  ARM: dts: vexpress: set the right partition type for NOR flash
  arm: dts: vexpress-v2p-ca15_a7: disable NOR flash node by default
  ARM: dts: vexpress-v2p-ca15_a7: update coresight DT bindings
