[PATCH v6 14/25] coresight: funnel: remove multiple init calls from funnel driver

[Tingwei Zhang]

From: Mian Yousaf Kaukab <ykaukab at suse.de>

Dynamic-funnel uses module_amba_driver to register. Whereas
static-funnel uses builtin_platform_driver. Combine these init calls
into a single module_init/exit pair in preparation to make the driver
modular.
