e350f76c66 Bring in the last round of updates before adding the interrupt support. 
Fix the following issues:

- Removed revision from device softc, it isn't used anywhere else out of
  device attach routine;

- Move the duplicated code for verification of valid banks (and pins) to
  a single function;

- Use some macros to simplify the handling of some constants;

- Update some stale comments.

0236b3314f Revert a glitched mismerge that got caught up in the prior commit. 
The PJ4B family is still armv7, not armv6.

6783238b2d Define the old-school arm arch constants we still use internally based on 
the somewhat newer constants predefined by the compiler.  This will allow
userland apps to use various machine/foo.h headers without CPUTYPE defined.

3b9e64af65 Do not return the total number of available pins but the maximum pin number 
we can cope.

Previously the returned value could prevent access to some of the pins.

c15882f091 Remove the old NFS client and server from head, 
which means that the NFSCLIENT and NFSSERVER
kernel options will no longer work. This commit
only removes the kernel components. Removal of
unused code in the user utilities will be done
later. This commit does not include an addition
to UPDATING, but that will be committed in a
few minutes.

c18b81e54b Fix the unwinder to get past functions with no stack but may cause an 
exception. In this case no registers will be updated but the link register
will be copied to the program counter to be used to find the calling
function. In this case the program counter may be updated and we should
continue with the trace.

61bc42f782 Add a new sdhci quirk, SDHCI_QUIRK_WAITFOR_RESET_ASSERTED, to work around 
TI OMAP controllers which will return the reset-in-progress bit as zero if
you read the status register too fast after setting the reset bit.

The zero is apparently from a stale snapshot of the internal state presented
in the interface register, and leads to a false indication that the reset
is complete when it either hasn't started yet or is in-progress.  The
workaround is to first loop until the bit is seen as asserted, then do the
normal loop waiting to see it de-asserted.

7f353dddc8 Fix the watchdog timeout calculation to prevent wrap. The RPi hardware 
can't do a timeout bigger than 15 seconds.  The code wasn't checking for
this and because bitmasking was involved the requested timeout was
basically adjusted modulo-16.  That led to things like a 128 second
timeout actually being a 9 second timeout, which accidentally worked fine
until watchdogd was changed to only pet the dog once every 10 seconds.
