For multi-byte ACPI memmap reads, we previously had a mutex to ensure data continuity. A better approach is to use a read cache. Since the kernel will enable burst mode before reading a multi-byte memmap variable and disable it afterward, we can populate the cache on the first read after enabling burst. This solution removes deadlock bugs, is contained entirely in acpi.c, and saves a deferred function. BUG=chromium:514283 TEST=Manual on Glados. Add prints in acpi_read, verify that multi-byte reads come from cache and non-burst reads continue to function as before.
