[PATCH option A] bcma: use custom printing functions

["Rafał Miłecki" <zajec5@gmail.com>]

Having bus number printed makes it much easier to anaylze logs on
systems with more buses. For example Netgear WNDR4500 has 3 AMBA buses
in total, which makes standard log really messy.
---
This patch (option A) keeps using pr_<level> in custom functions.

Pros: We use prefered functions (pr_<level>) in custom functions
Cons: Sometimes we may need to call pr_<level> directly. We won't get
	messages prefixed then (because of not setting pr_fmt).
