dt-bindings: mmc: sdhci-msm: allow flexible order of optional clocks
The Qualcomm SDHCI controller lists optional clocks, but still expects
fixed order of them and does not allow to skip such clocks if further
one in the list is needed. These optional clocks are truly optional,
so we need to allow the list to have different orders. The clocks are:
- ice: used for Inline Crypto Engine, which is actually separate block
and merging it with SDHCI is not a requirement,
- bus: clock for SDCC bus frequency voting,
- cal and sleep: used for RCLK delay calibration and required for
certain platforms for such calibration (as expressed in original
commit 4946b3af5e8e ("mmc: sdhci-msm: Enable delay circuit
calibration clocks")). Only MSM8974pro has these clocks.
Relaxing the order fixes dtbs_check warnings:
qcom-msm8974pro-fairphone-fp2.dtb: mmc@f9824900: clock-names:3: 'ice' was expected
qcom-msm8974pro-fairphone-fp2.dtb: mmc@f9824900: clock-names:4: 'bus' was expected
