SATI translation layer was incorrectly using allocation length instead
of blocks, and was constructing the ATA command incorrectly.
Also change #define to specify that the 512 block size here is
specific for DOWNLOAD_MICROCODE, and does not relate to the device's
logical block size.

Generally this check is not needed anymore, as there is not a legitimate
case where curthread != NULL, after pcpu 0 area has been properly

- Add constants for the rest of the fields in the PCI-express device
capability and control registers.
- Tweak some of the recently added PCI-e capability constants (always
use hex for offsets in config space, and include a shortened
version of the relevant register in the name of field constants).

I'm not sure where in the deep, distant past I found the AR_PHY_MODE
registers for half/quarter rate mode, but unfortunately that doesn't
seem to work "right" for non-AR9280 chips.
Specifically:
* don't touch AR_PHY_MODE
* set the PLL bits when configuring half/quarter rate
I've verified this on the AR9280 (5ghz fast clock) and the AR5416.
The AR9280 works in both half/quarter rate; the AR5416 unfortunately
only currently works at half rate. It fails to calibrate on quarter rate.
No, this isn't HT/5 and HT/10 support. This is the 11a half/quarter
rate support primarily used by the 4.9GHz and GSM band regulatory
domains.
This is definitely a work in progress.
TODO:
* everything in the last commit;
* lots more interoperability testing with the AR5212 half/quarter rate
support for the relevant chips;
* Do some interop testing on half/quarter rate support between _all_
the 11n chips - AR5416, AR9160, AR9280 (and AR9285/AR9287 when 2GHz
half/quarter rate support is coded up.)
used when running the chips in half/quarter rate.
This sets up some default parameters which are then overridden by the
driver (which manually configures things like slot timing at interface
start time.)
Although this is a copy-and-modify from the AR5212 HAL, I did peek
at the reference HAL and the ath9k driver to see what they did.
Ath9k in particular doesn't hard-code this - instead, their version
of ar5416InitUserSettings() does all of the relevant math.
TODO:
* do the math, not hard code things!
* fix the mac clock calculation for the AR9287; since it runs the
MAC clock at a higher rate, requiring all the duration calculations
to change;
* Do a whole lot more validation for half/quarter rates.

Some of the math is a little wrong thanks to clocks in 11a mode running
at 44MHz when in fast clock mode (rather than 40MHz, which the chips
before AR9280 ran 11a in). That'll have to be addressed in a future commit.
This fixes the incorrect slot (and likely ACK/RTS timeout) values
which I see when enabling half/quarter rate support on the AR9280.
The resulting math matches the expected calculated default values.
of the DWC OTG is very simple in PIO mode, and we need to re-transmit
data when NAK is received among other things. We probably will need
to implement some kind of rate limitation on the NAK-ing.
drivers:
- Remove scsi_low_pisa.*, they were unused.
- Remove <compat/netbsd/physio_proc.h> and calls to the stubs in that
header. They were empty nops.
- Retire sl_xname and use device_get_nameunit() and device_printf() with
the underlying device_t instead.
- Remove unused {ct,ncv,nsp,stg}print() functions.
- Remove empty SOFT_INTR_REQUIRED() macro and the unused sl_irq member.

The DWC OTG host mode support should still be considered
experimental. Isochronous support for DWC OTG is not
fully implemented. Some code added derives from
Aleksandr Rybalko's dotg.c driver.
ath_buf and when forming a non-aggregate frame.
The non-11n setds function is called when TXing aggregate frames (and
yes, I should fix this!) and the non-11n TX aggregation code doesn't clear
the delimiter field. I figure it's nicer to do that.
This had the side effect of clearing HAL_TXDESC_CLRDMASK for a bunch of
frames, meaning they'd end up being potentially filtered if there were
an error. This is fine in the previous world as they'd just be
software retried but now that I'm working on filtered frames, these
descriptors would be endlessly retried until another valid frame would
come along that had CLRDMASK set.

with the correct configuration.
Occasionally an aggregate TX would fail and the first frame would be
retransmitted as a non-AMPDU frame. Since bfs_aggr=1 and bfs_nframes > 1
(from the previous AMPDU attempt), the aggr completion function would be
called and be very confused about what's going on.
