dt-bindings: PCI: mediatek-gen3: Allow exact number of clocks only
[ Upstream commit 5efa23224bf573d4bceb51bc646dd67b6ccb83b5 ]
In MediaTek PCIe gen3 bindings, "clocks" accepts a range of 1-6 clocks
across all SoCs. But in practice, each SoC requires a particular number of
clocks as defined in "clock-names", and the length of "clocks" and
"clock-names" can be inconsistent with current bindings.
For example:
- MT8188, MT8192 and MT8195 all require 6 clocks, while the bindings
accept 4-6 clocks.
- MT7986 requires 4 clocks, while the bindings accept 4-6 clocks.
Update minItems and maxItems properties for individual SoCs as needed to
only accept the correct number of clocks.
