[ Upstream commit e23d86c49a9c78e8dbe3abff20b30812b26ab427 ]
Add minItems constraint to interconnect-names as well. The schema
currently tries to match 2 names and fail for DTs with single entry.
With the change applied, below interconnect-names values are possible:
['qspi-config'], ['qspi-config', 'qspi-memory']
Fixes: 8f9c291558 ("dt-bindings: spi: Add interconnect binding for QSPI")
