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 4946b3af ("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
