This zeros out all microcode related memory before loading
the microcode.
This also fixes initialization of the MAC control register.
The _only_ place where we overwrite the contents of the MAC control
register is at the beginning of b43_chip_init().
All other places must do read() -> mask/set -> write() to not
overwrite existing bits.
This also adds a longer delay for waiting for the microcode
to initialize itself. It seems that the current timeout is sufficient
on all available devices, but there's no real reason why we shouldn't
wait for up to one second. Slow embedded devices might exist.
Better safe than sorry.
While at it, fix naming of MACCTL values.
This patch by Michael Buesch has been ported to b43legacy.

This fixes a sparse warning about weird locking.
The spinlock is not needed, so simply remove it.
This also adds some sanity checks to the PHY and radio locking
to protect against recursive locking.

This fixes extraction of some values from the SPROM.
It mainly fixes extraction of antenna related values, which
is needed for another b43 fix sent later.

This adds support for turning the radio off in software.
That's useful in environments, where you don't want the RF
to radiate any signals, but don't want to bring the interface down.
This patch is based on a similar patch of b43 by Michael Buesch.
