Coresight TMC splits 64bit registers into a pair of 32bit registers
(e.g DBA, RRP, RWP). Provide helpers to read/write to these registers.

The Coresight SoC 600 TMC ETR supports save-restore feature,
where the values of the RRP/RWP and STS.Full are retained
when it leaves the Disabled state. Hence, we must program the
RRP/RWP and STS.Full to a proper value. For now, set the RRP/RWP
to the base address of the buffer and clear the STS.F
Coresight SoC 600 defines a new configuration for TMC, Embedded Trace
Streamer (ETS), indicated by 0x3 in MODE:CONFIG_TYPE. Make sure
the driver handles the new type properly.

This patch adds description of the capabilities of a given TMC.
This will help us to handle different versions of the TMC in the
same driver by checking the capabilities.

The coresight SoC 600 supports ETR save-restore and also supports
a new mode, SWFIFO2, which helps to streaming the trace data through
a functional I/O (e.g, USB).
Also, TMCs have different PIDs in different configurations (ETF,
ETB & ETR), unlike the previous generation.

As per coresight standards, PIDR2 register has the following format :

[3]- JEDEC, designer ID is specified by JEDEC.
However some of the drivers only use mask of 0x3 for the PIDR2 leaving
bits [3-2] unchecked, which could potentially match the component for

The Linux coresight drivers define the programmable ATB replicator as
