Disable WEP hardware encryption on the AR5210, in order to allow other
encryption types.

The AR5210 only has four WEP key slots, in contrast to what the
later MACs have (ie, the keycache.) So there's no way to store a "clear"
key.

Even if the driver is taught to not allocate CLR key entries for
the AR5210, the hardware will actually attempt to decode the encrypted
frames with the (likely all 0!) WEP keys.

So for now, disable the hardware encryption entirely and just so it
all in software. That allows both WEP -and- WPA to actually work.

If someone wishes to try and make hardware WEP _but_ software WPA work,
they'll have to create a HAL capability to enable/disable hardware
encryption based on the current STA/Hostap mode. However, making
multi-vap work with one WEP and one WPA VAP will require hardware
encryption to be disabled anyway.

Reapply r228785 now it has been tested by Adrian. Also add comments
with the old AR_SCR_SLE_XXX values, with a short explanation why they
were changed.

The AR_SCR_SLE_{WAKE,SLP,NORM} values are pre-shifted in ar5210reg.h and
ar5211reg.h, while they should be unshifted, like in ar5212reg.h. Then,
when the OS_REG_RMW_FIELD() macro shifts them again, the values will
overflow, becoming effectively zero.
