Some devices like the Netgear WGT634u are using minuses between the blocks
of the MAC address and other devices are using colons to separate them.

Instead of writing own function for parsing the mac address we now
use sscanf.

Nvram_getenv should behave like cfe_getenv. cfe_getenv returns 0 on
success and -9 if the value was not found. If the input was wrong -8
will be returned by cfe_getenv. Change nvram_getenv to do the same.

When trying to netboot a Linksys WRT54GS WLAN router, the bootup fails,
because of following error message:
...
[ 0.424000] b44: b44.c:v2.0
[ 0.424000] b44: Invalid MAC address found in EEPROM
[ 0.432000] b44 ssb0:1: Problem fetching invariants of chip,aborting
[ 0.436000] b44: probe of ssb0:1 failed with error -22
...
The router uses a CFE bootloader, but most of the needed environment
variables for network card initialization, are not available from CFE
via printenv and even though not via cfe_getenv().
The required environment variables are saved in a special partition
in flash memory. The attached patch implement nvram_getenv and enables
bootup via NFS root on my router.
Most of the patch is extracted from the OpenWrt subversion repository and
stripped down and cleaned up to just fix this issue.
[Ralf: sorted out header file inclusions. Lots of unneded headers and such
that should have been included.]

The GPIO API is supposed to return 0 or a negative error code,
but the SSB GPIO functions return the bitmask of the GPIO register.
Fix this by ignoring the bitmask and always returning 0. The SSB GPIO functions can't fail.

This patch simplifies the BCM47xx GPIO code by using the new SSB GPIO
API, which does a lot things that were implemented directly in the
BCM47xx code.
