This adds a new Kconfig option for enabling probing of N-PHYs.
This option will be removed again once the stuff works.
For now it is to help in development. This way real users won't
execute the broken N-PHY codepaths, but the developers can easily
enable N-PHY stuff.
To enable N-PHY probing simply remove the BROKEN dependency
and enable the option in the kernel config.

Remove b43 PIO support.
DMA works well on all supported devices. There's no reason to use PIO.
Additionally, new devices don't support PIO in hardware anymore.
b43 PIO support is dead and unused code.
After applying this patch please do
git rm drivers/net/wireless/b43/pio.h
git rm drivers/net/wireless/b43/pio.c
to remove the main PIO support code.

This fixes lowlevel register access for PCMCIA based devices.
The patch also adds a temporary workaround for the device mac address.
It simply adds generation of a random address. The real SPROM extraction
will follow in another patch.
The temporary workaround will be removed then, but for now it's OK.

Reviewing the semaphore usage I noticed these down_interruptible calls. Most
of these aren't returning anything, so a caller can't tell if the operation
completed or not. prism54_wpa_bss_ie_get() returns zero, but it's treated as
the function failing which doesn't seem correct.

This turns out to be true only for rtl8180. On rtl8187, power levels are
indeed stored in nibbles, so this patch is wrong. Please revert this patch.

bugs galore:
* 0xf380 instead of htons(ETH_P_AARP), etc. Works only on l-e.
* back in 2.3.20 driver got readb() and friends instead of
direct dereferencing of iomem. Somebody got too enthusiatic and replaced
ntohs(p->mrx_overflow)
with
ntohs(read(&p->mrx_overflow)
without noticing that (a) the sucker is 16bit and (b) that expression can't possibly
be portable anyway (hell, on l-e it's always less than 256, on b-e it's always a
multiple of 256). Proper fix is
swab16(readw(&p->mrx_overflow)
taking into account the conversion done by readw() itself. That crap happened
in several places; the same fix applies.
* untranslate() assumes little-endian almost everywhere, except for
the code checking for IPX/AARP packets; there we forgot ntohs(), so that part
only works on big-endian.

On big-endian we end up with swapped first two bytes in packet,
due to earlier conversion to host-endian and forgotten conversion
back.
The code we calculated that host-endian for had been duplicated
several time - it finds the 802.11 MAC header length by the first
two bytes of packet; taken into a new helper (header_len(__le16 ctl)).
