Revert "swconfig: fix Broadcom b53 support"
This reverts commit 8f9cd1af0f9c325a902dbd0e79e12015372e6bb0.
That commit was meant to add a single EXPORT_SYMBOL_GPL() but it
actually also added few .of_match_table-s. One commit should handle one
thing and should not introduce unrelated changes.
Regarding actual changes:
1. EXPORT_SYMBOL_GPL is not required as we don't build swconfig drivers
as modules.
2. PHY drivers must not have .of_match_table. That is allowed for MDIO
drivers. This could work for some time (although is didn't for me on
bcm53xx) but does not with kernel 5.10. It causes a soft lockup and
upstream developers confirmed it's an unsupported design.
