x86: acpi: Split out context creation from base tables
At present acpi_setup_base_tables() both sets up the ACPI context and
writes out the base tables.
We want to use an ACPI writer to write the base tables, so split this
function into two, with acpi_setup_ctx() doing the context set, and
acpi_setup_base_tables() just doing the base tables.
Disable the writer's write_acpi_tables() function for now, to avoid
build errors. It is enabled in a following patch.
