x86/amd_nb: Fix compile-testing without CONFIG_AMD_NB
node_to_amd_nb() is defined to NULL in non-AMD configs:
drivers/platform/x86/amd/hsmp/plat.c: In function 'init_platform_device':
drivers/platform/x86/amd/hsmp/plat.c:165:68: error: dereferencing 'void *' pointer [-Werror]
165 | sock->root = node_to_amd_nb(i)->root;
| ^~
drivers/platform/x86/amd/hsmp/plat.c:165:68: error: request for member 'root' in something not a structure or union
Users of the interface who also allow COMPILE_TEST will cause the above build
error so provide an inline stub to fix that.
