qc->n_iter was used for libata's own sg walking before sg chaining
replaced it. During conversion, the field and its usage in sata_fsl
were left behind. Kill the filed and update sata_fsl.

AHCI uses CAP.NP to indicate the number of ports and PI to tell which
ports are enabled. The only requirement is that the number of ports
indicated by CAP.NP should equal or be higher than the number of
enabled ports in PI.
CAP.NP and PI carry duplicate information and there have been some
interesting cases. Some early AHCI controllers didn't set PI at all
and just implement from port 0 to CAP.NP. An ICH8 board which wired
four out of six available ports had 3 (4 ports) for CAP.NP and 0x33
for PI. While ESB2 has less bits set in PI than the value in CAP.NP.
Till now, ahci driver assumed that PI is invalid if it doesn't match
CAP.NP exactly. This violates AHCI standard and the driver ends up
accessing unmimplemented ports on ESB2.
This patch updates CAP.NP and PI handling such that PI can have less
number of bits set than indicated in CAP.NP and the highest port is
determined as the maximum port of what CAP.NP and PI indicate.

Teach the debug logging macro to differentiate between log levels based on the
type of debug level enabled specifically instead of a threshold-based one.
Thus, convert tape->debug_level to a bitmask that is written to over /proc.
Also,
- cleanup and simplify the debug macro thus removing a lot of code lines,
- get rid of unused debug levels,
- adjust the loglevel at several places where it was simply missing (e.g.
idetape_chrdev_open())
- move the tape ptr initialization up in idetape_chrdev_open() so that we can
use it in the debug_log macro earlier in the function.

The commit 139ddfcab5 ("ide: move handling of
I/O resources out of ide_probe_port()") changed the ordering of hwif->noprobe
check vs ide_hwif_request_regions() call (so that we now reserve I/O regions
before checking for hwif->noprobe). However ide-generic host driver depended
on hwif->noprobe to be set for skipping probing of empty ide_hwifs[] slots.
Fix it by passing only indexes of non-empty slots to ide_device_add_all()
from ide_generic_init().

Redo the calculation of NR_syscalls since that disappeared from i386 and
use a similar mechanism on x86_64.
We now figure out the size of the system call table in arch code and stick
that in syscall_table_size. arch/um/kernel/skas/syscall.c defines
NR_syscalls in terms of that since its the only thing that needs to know
how many system calls there are.
The old mechananism that was used on x86_64 is gone.
arch/um/include/sysdep-i386/syscalls.h got some formatting since I was
looking at it.
