drm/radeon: remove useless and potentially wrong message

There is no need to repeat information that printed by PCI core at boot time.

Besides that printing was potentially wrong since resource_size_t might be
bigger than 32 bits and there is a dedicated specifier for such type, i.e.
%pap. Someone can fix it and use even better approach, i.e. %pR.

7 years agodrm: Use pr_cont where appropriate

drm: Use pr_cont where appropriate

Using 'printk("\n")' is not preferred anymore and
using printk to continue logging messages now produces
multiple line logging output unless the continuations
use KERN_CONT.

Convert these uses to appropriately use pr_cont or a
single printk where possible.

Miscellanea:

o Use a temporary const char * instead of multiple printks
o Remove trailing space from logging by using a leading space instead

There still seem to be some blocks that make accesses

this.
