acpi: build_dmar_q35: use acpi_table_begin()/acpi_table_end() instead of build_header()

it replaces error-prone pointer arithmetic for build_header() API,
with 2 calls to start and finish table creation,
which hides offsets magic from API user.

While at it switch to build_append_int_noprefix() to build
table entries tables.
