[PATCH 1/1] arm64: zynqmp: Add CoreSight components

["Wojciech Żmuda" <wzmuda@n7space.com>]

From: Wojciech Zmuda <wzmuda@n7space.com>

Add nodes for the following CoreSight components:
 - ETMs for A53 cores
 - debug components for A53 cores
 - funnel gathering outputs from A53 ETMs and SoC-wide funnels
 - the only replicator
 - all TMCs: 4k ETF, 8k ETF and ETR
 - TPIU
