AGESA S3: Refactor S3 backup store locations in SPI

Prepare code to locate S3 backup from CBFS as a file. Follow-up will
replace remaining use of CONFIG_S3_DATA_POS with cbfs_get_file_content().

AGESA: Clean separation of SPI flash

To be precise, wakeup from S3 does not involve SPI writing, while
preparing for it on cold power-ons currently does.

For S3DataTypeMtrr storage is changed such that the first 4 bytes
is the length of data stored like with the other two S3DataType.

AGESA boards: Use acpi_s3_resume_allowed()

This adds use of BROKEN_CAR_MIGRATE to include CBMEM symbols for the
build of romstage also for boards without HAVE_ACPI_RESUME.
These symbols got exposed as the use of preprocessor directives was
reduced.

We expect the linker to do a fair job and optimize away function
bodies that are on unreachable execution paths.

AGESA: Add agesawrapper_post_device()

NOTE: The procedure is moved across a collected timestamp
TS_WRITE_TABLES, so the delay of SPI erase/write will be accounted
for in an earlier entry in cbmem -t output.

AGESA: Call get_bus_conf() just once

Instead of calling get_bus_conf() three times from write_tables()
and executing it once, just make one call before entering write_tables().
