changes v4:
- integrate microchip feedback to the ksz9477_drive_strengths comment.
- add Reviewed-by: Rob Herring <robh@kernel.org>

changes v3:
- yaml: use enum instead of min/max
- do not use snprintf() on overlapping buffer.
- unify ksz_drive_strength_to_reg() and ksz_drive_strength_error(). Make
it usable for KSZ9477 and KSZ8830 variants.
- use ksz_rmw8() in ksz9477_drive_strength_write()

changes v2:
- make it work on all know KSZ* variants except of undocumented LAN*
switches
- add io-drive-strength compatible for ksz88xx chips
- test exact drive strength instead of nearest closest.
- add comment and refactor the code
