x86/sev: Add missing __init annotations to SEV init routines

Browse source

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.
