Subject: [PATCH] The API for loading tables changed (we no longer explicitly
 search for the RSDP, it's now found via a callback).

AcpiOsSleepUsec() went away, use AcpiOsSleep() instead (we could use
AcpiOsStall() too)

AcpiFormatException() was changed to make more sense (it behaves like
our old acpi_strerror() did), so throw acpi_strerror() away (still
#defined in acpivar.h though, we need to sweep these seperately).
