x86/sev: Add missing __init annotations to SEV init routines
Currently, get_secrets_page() is only reachable from the following call chain: __init snp_init_platform_device(): get_secrets_page() so mark it as __init as well. This is also needed since it calls early_memremap(), which is also an __init routine. Similarly, get_jump_table_addr() is only reachable from the following call chain: __init setup_real_mode(): sme_sev_setup_real_mode(): sev_es_setup_ap_jump_table(): get_jump_table_addr() so mark get_jump_table_addr() and everything up that call chain as __init as well. This is also needed since future patches will add a call to get_secrets_page(), which needs to be __init due to the reasons stated above.
