ichsmb(4), tco(4): Add support for TCO on newer Intel chipsets.

TCO (`Total Cost of Ownership', Intel's bizarre name for a watchdog
timer) used to hang off the Intel I/O platform controller hub's (ICH)
low-pin-count interface bridge (LPC IB), or ichlpcib(4).  On newer
devices, it hangs off the ICH SMBus instead.
Tested on INTEL 100SERIES_SMB (works) and INTEL 100SERIES_LP_SMB
(doesn't work, still not sure why).

XXX kernel revbump: This breaks the module ABI -- tco(4) modules
older than the change to make ta_has_rcba into ta_version will
incorrectly attach at buses they do not understand.  (However, the
tco(4) driver is statically built into GENERIC, so maybe it's safe
for pullup since the module wouldn't have worked anyway.)
