meta-digi-arm: u-boot: fix trustfence checks logic 

There are several possible values for TRUSTFENCE_UBOOT_ENV_DEK:

* Not defined: if the trustfence support is not included.
               Should not include the feature.
* 32 characters: when defining a valid key.
                 Should include the feature.
* "0": when explicitly disabling the feature.
       Should not include the feature
* <other>: Invalid value, should trigger the error.

This commits fixes the logic so that 'None' (no defined) is taken as a valid
value.
