ide: remove CONFIG_IDEDMA_{ICS,PCI}_AUTO config options
All modern distributions have been setting these options to "y" for ages.
(additionally "n" cases have been obsoleted for few years). Therefore use
DMA by default and remove CONFIG_IDEDMA_{ICS,PCI}_AUTO (also remove no longer
needed CONFIG_IDEDMA_AUTO). This fixes DMA support for rare configurations
where CONFIG_IDEDMA_{ICS,PCI}_AUTO was set to "n" but "hdparm -d 1" was used
to enable DMA support and which were forced to PIO mode by "ide: don't allow
DMA to be enabled if CONFIG_IDEDMA_{ICS,PCI}_AUTO=n" patch. There is no
functionality loss because "ide=nodma" kernel option is still available.
