base/node / ACPI: Enumerate node access class for 'struct access_coordinate'
[ Upstream commit 11270e526276ffad4c4237acb393da82a3287487 ]
Both generic node and HMAT handling code have been using magic numbers to
indicate access classes for 'struct access_coordinate'. Introduce enums to
enumerate the access0 and access1 classes shared by the two subsystems.
Update the function parameters and callers as appropriate to utilize the
new enum.
Access0 is named to ACCESS_COORDINATE_LOCAL in order to indicate that the
access class is for 'struct access_coordinate' between a target node and
the nearest initiator node.
Access1 is named to ACCESS_COORDINATE_CPU in order to indicate that the
access class is for 'struct access_coordinate' between a target node and
the nearest CPU node.
