Use DEVICE_ATTR_ADMIN_RW() helper macro instead of DEVICE_ATTR(), making
it simpler and easier to read.

Because the read and write function names of the sysfs attribute have been
normalized, there is a natural association.

mmiowb() is now implied by spin_unlock() on architectures that require
it, so there is no reason to call it from driver code. This patch was
generated using coccinelle:

	@mmiowb@
	@@
	- mmiowb();

and invoked as:

$ for d in drivers include/linux/qed sound; do \
spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done

NOTE: mmiowb() has only ever guaranteed ordering in conjunction with
spin_unlock(). However, pairing each mmiowb() removal in this patch with
the corresponding call to spin_unlock() is not at all trivial, so there
is a small chance that this change may regress any drivers incorrectly
relying on mmiowb() to order MMIO writes between CPUs using lock-free
synchronisation. If you've ended up bisecting to this commit, you can
reintroduce the mmiowb() calls using wmb() instead, which should restore
the old behaviour on all architectures other than some esoteric ia64
systems.

Use the standard WARN_ON instead.
If a small kernel is desired, WARN_ON can be disabled globally.

Also remove SSB_DEBUG. Besides WARN_ON it only adds a tiny debug check.
Include this check unconditionally.

Replace the ssb printk wrappers by standard print helpers.
Also remove SSB_SILENT. Nobody should use it anyway.

Use a more current logging style.

Convert ssb_dbprint to ssb_dbg too.

There is no 2.4 GHz or 5GHz antenna gain stored in sprom. The sprom
just stores the gain values for antenna 1 and 2 or 1 to 4 for more
recent sprom versions. On old devices antenna 2 was used for 5 GHz wifi.

This fixes parsing of the device invariants (MAC address)
for PCMCIA SSB devices.

ssb_pcmcia_do_get_invariants expects an iv pointer as data
argument.

pcmcia_enable_device() now replaces pcmcia_request_configuration().
Instead of config_req_t, all necessary flags are either passed as
a parameter to pcmcia_enable_device(), or (in rare circumstances)
set in struct pcmcia_device -> flags.

With the last remaining user of include/pcmcia/cs.h gone, remove
all references.
