[U-Boot] [PATCH 1/1] efi_driver: return type of efi_driver_init()

[Heinrich Schuchardt]

Change the return type of efi_driver_init() to efi_status_t.

efi_driver_init() calls efi_add_driver() which returns an efi_status_t
value. efi_driver_init() should not subject this value to a conversion to
int losing high bits on 64bit systems.
