x86: Move DSDT table to a writer function

Browse Source 
Move this table over to use a writer function, moving the code from the
x86 implementation.

Add a pointer to the DSDT in struct acpi_ctx so we can reference it later.

Disable this table for sandbox since we don't actually compile real ASL
code.
