ata: libata-core: Remove ata_port_resume_async()

Remove ata_port_resume_async() and replace it with a modified
ata_port_resume() taking an additional bool argument indicating if
ata EH resume operation should be executed synchronously or
asynchronously. With this change, the variable ata_port_resume_ehi is
not longer necessary and its value (ATA_EHI_XXX flags) passed directly
to ata_port_request_pm().
