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

Browse source 
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 (which also removes some manual offset
calculations).
