Rewrite of the bcm43xx initialization routines.
This fixes several issues:
* up-down-up-down-up... stale data issue
(May fix some DHCP issues)
* Fix the init vs IRQ handler race (and remove the workaround)
* Fix init for cards with multiple cores (APHY)
As softmac has no internal PHY handling (unlike dscape),
this adds the file "phymode" to sysfs.
The active PHY can be selected by writing either a, b or g
to this file. Current PHY can be determined by reading from it.
* Fix the controller restart code.
Controller restart can now also be triggered through
echo 1 > /debug/bcm43xx/ethX/restart

As many people don't seem to like the locking "obfuscation"
in the bcm43xx driver, this patch removes it.

This cleans up the bcm43xx sysfs code and makes it compliant
with the unwritten sysfs rules (at least I hope so).

This is the starting point to make the driver out-of-order-MMIO-stores safe.
There are more mmiowb() needed.
