Bartlomiej Zolnierkiewicz 7670df73fb ide: mode limiting fixes for user requested speed changes 
* Add an extra argument to ide_max_dma_mode() for passing requested transfer
  mode.  Use it as an upper limit when finding the best DMA for device/host.

* Rename ide_max_dma_mode() to ide_find_dma_mode() and at the same time add
  ide_max_dma_mode() wrapper which passes XFER_UDMA_6 as a requested mode to
  ide_find_dma_mode().  Also add inline ide_find_dma_mode() version for
  CONFIG_BLK_DEV_IDEDMA=n case.

* Pass requested transfer mode from ide_find_dma_mode() to ide_get_mode_mask()
  to avoid false warning from eighty_ninty_three().

* Use ide_find_dma_mode() to limit the user requested transfer mode in
  ide_rate_filter().  Also limit the requested mode by host max PIO mode.


Above changes make ide_rate_filter() to:

* Clip desired transfer mode down if it is invalid (values 0x0F, 0x13-0x19
  and 0x25-0x39, values > 0x46 were already clipped down, same for values
  0x25-0x39 but iff UDMA was not supported by the host).

* Clip desired transfer mode down if it is currently unsupported by IDE core
  (PIO6 and MWDMA3-4, the latter were already clipped down but iff UDMA was
  not supported by the host).

* Clip desired transfer mode down according to the host capabilities
  (UDMA modes were already clipped down but MWDMA/SWDMA/PIO weren't,
  also ->atapi_dma flag was not respected).

* Clip desired transfer mode down according to the device capabilities
  (except PIO modes for now which require mode work) - shouldn't be a
  problem since ide_set_xfer_rate() is called _after_ device has accepted
  given transfer mode.

and also result in a number of host driver specific bugfixes:

While at it:

* Use ide_rate_filter() in cs5520.c::cs5520_tune_chipset().

* Remove no longer needed checks from hpt366.c::hpt3{6,7}x_tune_chipset().
