Since the removal of the deprecated efivars sysfs interface there are
no users of the efivars kobject, which can be removed.

Included is also a related patch changing the return type of
efivar_supports_writes() to match the new efivar_is_available()
function.

Note that I intend to use efivar_is_available() in a driver with
optional EFI support (hence the dummy implementation) and the removal of
the kobject will simplify the upcoming Qualcomm UEFI Secure Application
driver somewhat too.
