o when turning off the socket for a 16-bit card, write 0 to INTR register
rather than just tying to just clear the rest bit. this seems to fix
card insert detection after an eject on TI bridges (ricoh bridges work
either way, apparently). This is a MFp4.
o Cope better with TOPIC95 bridges on powerup. According to NetBSD driver,
these bridges don't set POWER_STATE, so cope accordingly in our power
code. They also need a little extra time to settle, so do that as well.
o It appears that we need to turn on/off one of the clocks to the card
when we power up/down that socket on a TOPIC97, also from NetBSD.
o TOPIC97 bridges need to specifically enable LV card support. Unconditionally
do this in the hopes that all laptops that have these chips support LV
voltages (they should, since they are required for CardBus).
o TOPIC register name regularization. Registers specific to models of TOPIC
are now called out as such.

Enable the bits in this register so low voltage 16-bit cards may work.

Instead the threshould is initialized in device attach. Later the

WB (write-back) on x86 via control bits in PTEs and PDEs (including making
use of the PAT MSR). Changes include:
- A new pmap_mapdev_attr() function for amd64 and i386 which takes an
additional parameter (relative to pmap_mapdev()) specifying the cache
mode for this mapping. Note that on amd64 only WB mappings are done with
the direct map, all other modes result in a private mapping.
- pmap_mapdev() on i386 and amd64 now defaults to using UC (uncached)
mappings rather than WB. Previously we relied on the BIOS setting up
MTRR's to enforce memio regions being treated as UC. This might make
hw.cbb_start_memory unnecessary in some cases now for example.
- A new pmap_mapbios()/pmap_unmapbios() API has been added to allow places
that used pmap_mapdev() to map non-device memory (such as ACPI tables)
to do so using WB as before.
- A new pmap_change_attr() function for amd64 and i386 that changes the
caching mode for a range of KVA.
