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

[Anshuman Khandual]

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
