ide: remove ->ide_dma_check (take 2)
* Add IDE_HFLAG_TRUST_BIOS_FOR_DMA host flag for host drivers that depend
on BIOS for programming device/controller for DMA. Set it in cy82c693,
generic, ns87415, opti621 and trm290 host drivers.
* Add IDE_HFLAG_VDMA host flag for host drivers using VDMA. Set it in cs5520
host driver.
* Teach ide_tune_dma() about IDE_HFLAG_TRUST_BIOS_FOR_DMA flag.
* Add generic ide_dma_check() helper and remove all open coded ->ide_dma_check
implementations. Fix all places checking for presence of ->ide_dma_check
hook to check for ->ide_dma_on instead.
* Remove no longer needed code from config_drive_for_dma().
* Make ide_tune_dma() static.
v2:
* Fix config_drive_for_dma() return values.
* Fix ide-dma.c build for CONFIG_BLK_DEV_IDEDMA_PCI=n by adding
dummy config_drive_for_dma() inline.
* Fix IDE_HFLAG_TRUST_BIOS_FOR_DMA handling in ide_dma_check().
* Fix init_hwif_it8213() comment.
There should be no functionality changes caused by this patch.
