soc/amd/stoneyridge/smihandler: add PSP SMI handler
Now that the PSP SMI handler for flash access is also implemented for the PSP generation 1, the PSP SMI handler can be added to the Stoneyridge code too. The actual PSP SMI handler code will only be added to the build when SOC_AMD_COMMON_BLOCK_PSP_SMI is selected which isn't the default case, so this patch doesn't change the current behavior unless that option is also selected. This SMI handler mainly added for completeness since the PSP firmware blobs released for Stoneyridge are probably lacking the corresponding PSP-side code to send the PSP SMI to the host. At least if I remember correctly the PSP bootloader release for Stoneyridge has the ability to load the secure OS removed and since the secure OS is the runtime component, some part of that is probably what's sending those SMIs to the host. If there are some other PSP bootloader builds that support loading the secure OS, this patch might still be useful for those.
