Some components can continue to operate in the face of the SuperIO
controller being unavailable on the LPC bus (specifically, the UART and
boot flag processing). Other components require it present (AST-based
SFC implementations and the AST mailbox). Components in the latter
category can just fail with an errl when they attempt to access the
controller, but for those in the former category we add an isAvailable()
function in the SIO namespace to sidestep dealing with errors.
Specifically, isAvailable() tests for the expected error when the
SuperIO controller is disabled, and returns an errlHndl_t if any other
error occurs. This way true LPC errors are propagated to the caller to
commit as desired.
For the moment *all* errors produced by the SIO::isAvailable() LPC bus
access will result in the SIO code assuming the device is absent. We
should be more precise about this, but the hardware behaviour seen under
hostboot currently prevents us from being more specific. This problem is
highlighted by a FIXME block in the implementation of
SIO::isAvailable().

This reverts commit 627379aeaa27e30d66ebb0aecf218708d465162c, which
incorrectly attempted to account for LPC errors during testing for SIO
absence. The broken patch interprets the OPBM status as LPCHC status and
expects an LPCHC SYNC Abnormal error, however as it's the OPBM status
that indicates the error we never hit the LPCHC error path to populate
the errl with the error RC expected by the SIO driver.

The SuperIO driver makes accesses to the SIO chip from the console and
pnor module thread safe.
