Alex Deucher d054ac16ee drm/radeon/kms: make sure pci max read request size is valid on evergreen+ (v2)
If the bios or OS sets the pci max read request size to 0 or an
invalid value (6,7), it can result in a hang or slowdown.  Check
and set it to something sane if it's invalid.

v2: use pci reg defines from include/linux/pci_regs.h
