The reset controller support was added in
2b2c47d9e1fe90311b725125d6252a859ee87a79 ("ata: ahci_brcm: Allow
optional reset controller to be used") which was include in v4.20 and
newer so that explains the build failure.

You may want to cherry pick that change into the respective stable
branches and then back port the fixes if that is not too much trouble.
If that does not work or is impractical, please let me know and I can
provide directed backport changes for 4.9, 4.14 and 4.19.

Thank you
