that include chain, so include export.h explicitly now.

Nowadays we (almost) always store the currently executing command
in hwif->cmd so we can use it for the failed opcode reporting.

Simplify tf_read() method, making it deal only with 'struct ide_taskfile' and
the validity flags that the upper layer passes, and factoring out the code that
deals with the high order bytes into ide_tf_readback() to be called from the
only two functions interested, ide_complete_cmd() and ide_dump_sector().
This should stop the needless code duplication in this method and so make
it about twice smaller than it was; along with simplifying the setup for
the method call, this should save both time and space...

Make 'struct ide_taskfile' cover only 8 register values and thus put two such
fields ('tf' and 'hob') into 'struct ide_cmd', dropping unnecessary 'tf_array'
field from it.
This required changing the prototype of ide_get_lba_addr() and ide_tf_dump().

Replace IDE_TFLAG_{IN|OUT}_* flags meaning to the taskfile register validity on
input/output by the IDE_VALID_* flags and introduce 4 symmetric 8-bit register
validity indicator subfields, 'valid.{input/output}.{tf|hob}', into the 'struct
ide_cmd' instead of using the 'tf_flags' field for that purpose (this field can
then be turned from 32-bit into 8-bit one).

* Make IDE_TIMINGS and BLK_DEV_IDEDMA config options select IDE_XFER_MODE,
also add explicit selects for few host drivers that need it.

Make drive->id an unnamed union so id can be accessed either by using
'u16 *id' or 'struct hd_driveid *driveid'. Then convert all existing
drive->id users accordingly (using 'u16 *id' when possible).
This is an intermediate step to make ide 'struct hd_driveid'-free.

* Filter out "default" transfer mode values (0x00 - default PIO mode,
0x01 - default PIO mode w/ IORDY disabled) in write handler for obsoleted
/proc/ide/hd?/settings:current_speed setting.
Allowing "default" transfer mode values is a dangerous thing to do as
we don't support programming controller to the "default" transfer mode
and devices often use different values for the default and maximum PIO
mode (i.e. PIO2 default and PIO4 maximum) so the controller will stay
programmed for higher PIO mode while device will use the lower PIO mode.
There is no functionality loss as by using special IOCTLs device can
still be programmed to "default" transfer modes (it is only useful for
debugging/testing purposes anyway).
* Remove no longer needed IDE_HFLAG_ABUSE_SET_DMA_MODE host flag, it was
previously used by few host drivers to program the controller to PIO0
timings for "default" transfer mode == 0x01 (although some host drivers
would program invalid PIO timings instead).
* Cleanup ide_set_xfer_rate() and add BUG_ON().
