Change the text of the ATA_BMDMA prompt to indicate that it lets one access a class of device drivers (rather than only add a certain feature to libata). The divisions of the "ATA SFF support" menu now read - SFF controllers with custom DMA interface, - SFF controllers with bus master DMA (was: "ATA BMDMA support"), - SATA SFF controllers with BMDMA, - PATA SFF controllers with BMDMA, - PIO-only SFF controllers. This hopefully helps convince users of "make oldconfig" to follow the recommendation to switch that option on. Also let the help text of this prompt say more precisely what it is about: It adds a little bit of support code to libata that is required by many but not all SFF drivers. This option alone does not add support of respective controllers though; according drivers are chosen at subsequent dependent Kconfig prompts. --- And fix a typo.
