I'm still leaving out CONFIG_CORESIGHT_SOURCE_ETM4X because it depends
on the outcome of the investigation into CONFIG_PID_IN_CONTEXTIDR, but
I think we should enable these ones for now and start getting some of
the benefits sooner.

Changes since v1:

 * Remove CONFIG_CORESIGHT_CTI_INTEGRATION_REGS=y which shouldn't be
   enabled by default

-----

As suggested by Catalin here's the change to add Coresight to defconfig.

Unfortunately I don't think we should add CONFIG_CORESIGHT_SOURCE_ETM4X
which builds a few files until [1] is merged because of the overhead
of CONFIG_PID_IN_CONTEXTIDR.

[1]: https://lore.kernel.org/lkml/20211021134530.206216-1-leo.yan@linaro.org/T/

applies to arm64/for-next/core (e99db032d186)
