Paul Menzel a17ab7aba5 ata: ahci: Add support for AMD A85 FCH (Hudson D4) ...

Add support for the AMD A85 FCH (Hudson D4) AHCI adapter.

Since this adapter does not require the default 200 ms debounce delay
in sata_link_resume(), create a new board board_ahci_no_debounce_delay
with the link flag ATA_LFLAG_NO_DEBOUNCE_DELAY, and, for now, configure
the AMD A85 FCH (Hudson D4) to use it. On the ASUS F2A85-M PRO it
reduces the Linux kernel boot time by the expected 200 ms from 787 ms
to 585 ms.
