Subject: [PATCH V2 0/7] coresight: Move remaining AMBA ACPI devices into platform driver

This moves remaining AMBA ACPI devices into respective platform drivers for
enabling ACPI based power management support. This series applies on latest
coresight/next branch. This series has been built, and boot tested on a DT
based coresight platform. Although this still requires some more testing on
ACPI based coresight platforms.

Changes in V2:

- Dropped redundant devm_ioremap_resource() hunk from tmc_platform_probe()
- Defined coresight_[init|remove]_driver() for both AMBA/platform drivers
- Changed catu, tmc, tpiu, stm and debug coresight drivers to use the new
  helpers avoiding build issues arising from module_amba_driver(), and
  module_platform_driver() being on the same file

Changes in V1:

- Replaced all IS_ERR() instances with IS_ERR_OR_NULL() as per Suzuki
