Fix 2 infinite loops if IMC doesn't respond
ACPI code: The ACPI code is not currently being compiled in by default, but assuming that it will be at some point, I'm fixing the loop that waits for the IMC to respond after sending it a command. The loop now exits after 500ms, similar to the function in agesa. Agesa Code: a 16 bit variable will always be less than 100000. Change to be a 32 bit variable.
