[PATCH] dt-bindings: mfd: hisilicon: Fix Hi6421 SPMI compatible

["Rob Herring (Arm)" <robh@kernel.org>]

Use the hisilicon,hi6421-spmi compatible documented by the in-tree DTS
and matched by the Hi6421 SPMI PMIC driver. Also allow the GPIO
interrupt line property used by the HiKey970 PMIC node.

Assisted-by: LLM
Fixes: dee8a4e807dc ("dt-bindings: mfd: Convert hisilicon,hi6421-pmic to DT schema")
