fuse: revert birthtime support.

The creation time support breaks the data structures used in linux
fuse.  libfuse carries it's own header.

Revert the changes for now. We will try to get an agreement with the
fuse  upstream maintainers to avoid having to patch the library
headers all the time.
Add cast to (void *) to the following cases to suppress warnings by
-Wcast-align.  These do not increase the alignment requirement:

- rtm = (struct rt_msghdr *)(rtm + rtm->rtm_msglen)
- struct sockaddr *sa = &sa0; sX = (struct sockaddr_X *)sa
Show "default" for the zero-filled address consistently when nflag == 0.
- Simplify getaddr() and print_getmsg() by using RTAX_* instead of RTA_*
  as the argument.
- Reduce unnecessary loop in print_getmsg().
Fix address range specification with ifconfig(8) options such as:

- inet 192.0.2.1-10 netmask 255.255.255.0 (inet range spec + ifconfig options)
- inet6 2001:db8:1::1-f prefixlen 60 (inet6 range spec + ifconfig options)

If prefixlen or netmask option is specified with CIDR notation at
the same time, the option is used.

The NFSv4 server incorrectly assumed that the high order words of
the attribute bitmap argument would be non-zero. This caused an
interoperability problem for a recent patch to the Linux NFSv4 client.
The Linux folks have changed their patch to avoid this, but this
patch fixes the problem on the server.

Add two new CPU specific definitions - the watchdog clock frequency and
the UART clock frequency.

The AR933x and AR934x have separate PLL settings for these.
Initialise the watchdog and UART frequencies.

For all pre-AR933x chips, the frequency is just the APB frequency.
For the AR933x, the UART frequency is different but we just hacked around
it.

For the AR934x, there's a different PLL setting for these, so they have
to be broken out.
Use the UART frequency when programming the UART clock.

This allows the 16550 support to work correctly on the upcoming
AR934x support.
Teach the GPIO code about the AR934x GPIO register and pin counts.
Implement some initial AR934x support routines.

This code reads the PLL configuration registers and correctly programs
things so the UART and such can come up.

There's MIPS74k platform issues that need fixing; but this at least brings
things up enough to echo stuff out the serial port and allow for interactive
debugging with ddb.

Tested:

* AR71xx SoCs
* AR933x SoC
* AR9344 board (DB120)

Obtained from:	Qualcomm Atheros; Linux/OpenWRT
Add some initial board support for the AR934x and the Qualcomm Atheros
DB120 development board.

The AR934x SoCs are a MIPS74k based system with increased RAM addressing
space, some scratch-pad RAM, an improved gige switch PHY and 2x2 or 3x3
on-board dual-band wifi.

This support isn't complete by any stretch; it's just enough to bring
the board up for others to tinker with.  Notably, the MIPS74k support
is broken.  However it boots enough to echo some basic probe/attach
messages, before dying somewhere in the TLB code.

Thankyou to Qualcomm Atheros for their continued support of me doing
open source work with their hardware.

Tested:

* AR9344, mips74k
