libata: skip debounce delay on link resume
The link resume logic uses a 200msec delay while debouncing the SControl register. The rationale behind that delay is to accommodate some PHYs that behave badly if their SStatus/ SControl registers are pounded immediately on resume. The Broadcom STB SATA PHY does not seem to have this issue. This patch introduces a new link flag that allows platforms to skip the debounce delay if it isn't needed.
