soc/amd/common/block: Add support for common config for AMD SoCs
This change adds support for struct soc_amd_common_config that allows
multiple AMD SoCs to share common configuration. This can then be used
by common/block drivers to get the required configuration from device
tree. It also provides function declaration for
soc_get_common_config() that needs to be provided by SoCs making use
of the common configuration structure.
