acpi: add helper routines to initialize ACPI tables
Patch introduces acpi_table_begin()/ acpi_table_end() API
that hides pointer/offset arithmetic from user as opposed
to build_header(), to prevent errors caused by it [1].
acpi_table_begin():
initializes table header and keeps track of
table data/offsets
acpi_table_end():
sets actual table length and tells bios loader
where table is for the later initialization on
guest side.
