Log:
Batch of changes:
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.
# I need a machine with a TOPIC95 for testing.
