Clear unused (undocumented) CAM bytes while setting a key;
without that, hardware does weird things when A-MSDU bit in QoS header
is set.

Fix the following panic seen when migrating a FreeBSD guest on Xen:
panic: mtx_lock() of destroyed mutex @ /usr/src/sys/dev/fb/vesa.c:541
cpuid = 0

db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe001d2fa4f0

This is caused because vga_sub_configure (which is called if the VGA adapter
is attached after VESA tried to initialize), points to vesa_configure, which
doesn't initialize the VESA mutex. In order to fix it, make sure
vga_sub_configure points to vesa_load, so that all the needed vesa
components are properly initialized.

The 11n duration calculation function in net80211 and the HAL round /up/
the duration calculation for short-gi, so we can't use that.
The 11n duration calculation doesn't know about the extra symbol time
needed for STBC, nor the LDPC encoding duration, so we can't use
that.
This (along with other, local hacks) allow the locationing services to
get down to around 200nS (yes, nanoseconds) of variance when speaking
to a "good" AP.
Tested:
* AR9380, STA mode, local locationing frame hacks
In particular for me this fixes checksum problem when if_bridge attached
to the interface requests TXCSUM to be disabled, but effectively ignored.

- add new rman for prefetchable memory. Is used only if given 'ranges'
property contains prefetchable memory range.
- not all ranges in 'ranges' property are subject for rman's filling.
Tegra for example, have two addition records which are used for
'pci 'register' -> 'assigned-address' -> 'ranges' machinery.
Add sc_ranges_mask for masking not rman related ranges.
- consistently pass unknown (not managed at this level) resources
allocation/release/adjust requests to parent.

This is probably a NOP change since IS register is not activery used for
interrupts below the shared, but it looked odd to clear interrupts we did
not handle.
