3. There were two separate places dealing with port_map. Unify them
to one.
As all newer ahci chips seem to get PI correct and older ones usually
have zero PI. Controllers with holes in PI are very unlikely to screw
up PI, so #2 makes more sense than following inconsistent PI.
Without this change, not setting ATA_FLAG_HONOR_PI when it's needed

Currently, port configuration reporting has the following problems.
* iomapped address is reported instead of raw address
* report contains irrelevant fields or lacks necessary fields for

* host->irq/irq2 are there just for reporting and hacky.
This patch implements and uses ata_port_desc() and
ata_port_pbar_desc(). ata_port_desc() is almost identical to
ata_ehi_push_desc() except that it takes @ap instead of @ehi, has no
locking requirement, can only be used during host initialization and "
" is used as separator instead of ", ". ata_port_pbar_desc() is a
helper to ease reporting of a PCI BAR or an offsetted address into it.
LLD pushes whatever description it wants using the above two
functions. The accumulated description is printed on host
registration after "[S/P]ATA max MAX_XFERMODE ".
SFF init helpers and ata_host_activate() automatically add
descriptions for addresses and irq respectively, so only LLDs which
isn't standard SFF need to add custom descriptions. In many cases,
such controllers need to report different things anyway.

Debugging a report of a problem with an ancient solid state disk showed
up some problems in the IORDY handling
1. We check the wrong bit to see if the device has IORDY
2. Even then some ancient creaking piles of crap don't support
SETXFER at all.
The cases it fixes are obscure and the risk of side effects is slight

libata-link: update EH to deal with PMP links
Update ata_eh_autopsy(), ata_eh_report(),
ata_eh_revalidate_and_attach() and ata_eh_recover() to deal with PMP
links. ata_eh_autopsy() and ata_eh_report() updates are
straightforward. They just repeat the same operation over all
configured links. The only change to ata_eh_revalidate_and_attach()
is avoiding calling ->cable_select() on non-host ports.
ata_eh_recover() update is more complex as it first processes all
resets and then performs the rest. This is necessary as thawing with
some links in unknown state can be dangerous. ehi->action is cleared
on successful recovery of a link to avoid repeating recovery due to
failures in other links.
ata_eh_recover() iterates over only PMP links if PMP is attached, and,
on failure, the failing link is returned in @failed_link instead of
disabling devices directly. These are to integrate ata_eh_recover()
into PMP EH later.

We detect that the machine supports 1TB segments by looking at the

We don't currently use 1TB segments for user addresses < 1T, since
that would effectively prevent 32-bit processes from using huge pages
