Add PC_FLAG_DRQ_INTERRUPT pc flag, set it in ide*_do_request()
and check for it (instead of checking for IDE*_FLAG_DRQ_INTERRUPT)
in ide*_issue_pc(). This is a preparation for adding generic
ide_issue_pc() helper.
There should be no functional changes caused by this patch.

ide_do_drive_cmd is called only with ide_preempt action argument. So
we can remove the action argument in ide_do_drive_cmd and ide_action_t
typedef.
This patch also includes two minor cleanups: 1) ide_do_drive_cmd
always succeeds so we don't need the return value; 2) the callers use
blk_rq_init before ide_do_drive_cmd so there is no need to initialize
rq->errors.

Since scc_pata host driver no longer uses IDE PCI layer / ide_dma_setup()

Always call SELECT_MASK(..., 0) in ide_tf_load() (needs to be done
to match ide_set_irq(..., 1)) and then remove IDE_TFLAG_NO_SELECT_MASK
taskfile flag.
This change should only affect hpt366 and icside host drivers since
->maskproc(..., 0) for sgiioc4 is equivalent to ide_set_irq(..., 1).

ide_init_drive_cmd just calls blk_rq_init. This converts the users of
ide_init_drive_cmd to use blk_rq_init directly and removes
ide_init_drive_cmd.

Split out PCIC dependent code and SoC dependent code from board dependent
code. Now TX4927 PCIC code is independent from TX4927/TX4938 SoC code.
Also fix some build problems on CONFIG_PCI=n.
As a bonus, "FPCIB0 Backplane Support" is available for all TX39/TX49 boards
and PCI66 support is available for all TX49 boards.

SGI-IP28 is running in so called slow mode, when kernel is started
from the PROM. PROM calls must be done in slow mode otherwise the
PROM will issue an error. To get better memory performance we now
switch to normal mode, when the PROM is no longer needed.

The third operand to 'ins' must be a constant int, not a register.
[Ralf: The bug was actually intensional. Some versions used to throw an
error under certain circumstances for code like:
static inline void f(unsigned nr, unsigned *p)
{
unsigned short bit = nr & 5;
if (__builtin_constant_p(bit)) {
__asm__ __volatile__ (" foo %0, %1" : "=m" (*p) : "i" (bit));
} else {
/* Do something else. */
}
}
because gcc was not able to figure out that the "i" constraint was possibly
at the early stage when the constraint are getting verified. The solution
was using "ri" instead of "i". The "ri" would keep gcc happy but in the
end for code generation always the "i" constraint would be satisfied. The
problem afair originally appeared in the i386 io.h and also hit it's mips
equivalent. From there the workaround spread to many of the inline
assembler functions.]

Do not automatically "select" SCSI_DH for dm-multipath. If SCSI_DH
doesn't exist,just do not allow hardware handlers to be used.
Handle SCSI_DH being a module also. Make sure it doesn't allow DM_MULTIPATH
to be compiled in when SCSI_DH is a module.
