ata: enable quirk from jmicron JMB350 for JMB394

Browse source 
commit efb9e0f4f4 upstream.

Without the patch the kernel generates the following error.

 ata11.15: SATA link up 1.5 Gbps (SStatus 113 SControl 310)
 ata11.15: Port Multiplier vendor mismatch '0x197b' != '0x123'
 ata11.15: PMP revalidation failed (errno=-19)
 ata11.15: failed to recover PMP after 5 tries, giving up

This patch helps to bypass this error and the device becomes
functional.
