The 200 ms delay before debouncing the PHY in `sata_link_resume()` is
not needed for the Marvell 88SE9235.

So, remove it. Tested on IBM S822LC with current Linux 5.17-rc1:
Currently, without this patch (with 200 ms delay), device probe for ata1
takes 485 ms:

Looks good. Will apply to for-5.18.

Applied to for-5.18 with commit title and message changes. The title is now:
ata: ahci: Add support for Marvell 88SE9235 adapter
Since it is exactly what this patch is doing by adding a PCI ID.
The comments about the 200ms debounce delay not being needed is kept as
a description of how this new adapter support is defined, using the
board_ahci_no_debounce_delay board definition.
Thanks !

Thank you for applying the patch. I saw the summary/title change also
with the other patch. I am sorry, but I totally disagree. Reading that
summary/title in `git log --oneline`, it’s not clear at all, what the
patch does, and the full description or diff has to be read. “Add
support” for me means, that it was unsupported before, which is not true
at all as the defaults were used.

Right... I did not consider the final entry in the ahci_pci_tbl table
which matches against the device against the PCI AHCI storage class.
So right you are. I will restore your original commit title/message.
Thanks for checking.
