[PATCH v3] coresight: replicator: Use builtin_platform_driver()

[Vaishali Thakkar]

Macro builtin_platform_driver can be used for builtin drivers
that don't do anything in driver init. This file depends on
Kconfig CONFIG_CORESIGHT_LINKS_AND_SINKS which eventually
depends on CORESIGHT. Both CONFIG_CORESIGHT_LINKS_AND_SINKS and
CORESIGHT are bool. So, use builtin_platform_driver and remove
some boilerplate code.

Also, remove header file init.h as functionality like module_init
and module_exit is now relocated to module.h.

Changes since v1:
        - As per Mathieu's suggestion, remove the comment and
          code of Coccinelle
        - Also, add blank line before module_platform_driver
Changes since v2:
	- Use builtin_platform_driver instead of
	  module_platform_driver and change commit log and subject
	  accordingly.

Applied, thanks.
