[U-Boot] [PATCH v2 15/26] dm: pci: Drop the old version of pci_find_class()

[Simon Glass]

Move this function into the compatibility file so that it is not available
by default.

Signed-off-by: Simon Glass <sjg at chromium.org>

Changes in v2:
- Move the functions into pci_common.c so they can be used by old code
