efi: efivars: drop kobject from efivars_register()
Since commit 0f5b2c69a4cb ("efi: vars: Remove deprecated 'efivars' sysfs
interface") and the removal of the sysfs interface there are no users of
the efivars kobject.
Drop the kobject argument from efivars_register() and add a new
efivar_is_available() helper in favour of the old efivars_kobject().
Note that the new helper uses the prefix 'efivar' (i.e. without an 's')
for consistency with efivar_supports_writes() and the rest of the
interface (except the registration functions).
For the benefit of drivers with optional EFI support, also provide a
dummy implementation of efivar_is_available().
