PSOC6: do not remove QSPI from FUTURE_SEQUANA targets

Since QSPi is not yet supported by base TARGET_PSOC6,
there is no need to remove the device label from
FUTURE targets that inherit from TARGET_PSOC6.

This will need to be reverted back once the QSPI support
is implemented for Cypress PSOC6 targets.
