regulator: tps6594-regulator: remove hardcoded buck config

Commit 00c8265 ("regulator: tps6594-regulator: Add TI TPS65224 PMIC
regulators") added support for the TPS65224 and made the description of
the multi-phase buck converter variable depending on the variant of the
PMIC. But this was just done for MUTLI_BUCK12 and MULTI_BUCK12_34
configs probably because this variant only supports a multi-phase
configuration on buck 1 and 2. Remove the hardcoded value for the
remaining two configs, too as future PMIC variants might also support
these.

This is a preparation patch to refactor the regulator description and
is compile-time only tested.
