All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers

Every CPU has its own debug module and this module is used by JTAG
debugging and coresight tracing. If without enabling it, it's easily to
introduce lockup issue when we enable debugging features.

This patch is to enable CPU debug module when power on CPU; this allows
connecting to all cores through JTAG and used by kernel coresight
driver.
