x86/PCI: remove early PCI pr_debug statements
commit db635adc turned -DDEBUG for x86/pci on when CONFIG_PCI_DEBUG
is set. In general, I agree with that change.
However, it exposes a bunch of very low level PCI debugging in the
early x86 path, such as:
0 reading 2 from a: ffff
1 reading 2 from a: ffff
2 reading 2 from a: ffff
3 reading 2 from a: 300
3 reading 2 from 0: 1002
3 reading 2 from 2: 515e
These statements add a lot of noise to the boot and aren't likely to
be necessary even when handling random upstream bug reports.
[In contrast, statements such as these:
pci 0000:02:04.0: found [14e4:164a] class 000200 header type 00
pci 0000:02:04.0: reg 10: [mem 0xf8000000-0xf9ffffff 64bit]
pci 0000:02:04.0: reg 30: [mem 0x00000000-0x0001ffff pref]
are indeed useful when remote debugging users' machines]
Remove the noisy printks and save electrons everywhere.
