soc/amd/common: Rename spi.c and add prototype

The common/spi.c file contains a function for storing S3 data into flash
during POST.  In preparation for supporting S3, rename the file and add
a prototype for the one function.  Also change its build dependency to
CONFIG_HAVE_ACPI_RESUME.  This will be the only mechanism for supporting
S3 in subsequent patches.
