scsi: ufs: qcom: dt-bindings: Split SM8650 and similar

The binding for Qualcomm SoC UFS controllers grew and it will grow
further.  Split SM8650 and SM8750 UFS controllers which:

 1. Do not reference ICE as IO address space, but as phandle,

 2. Have same order of clocks.

 3. Have MCQ I/O address space. Document that MCQ address space as
    optional to maintain backwards compatibility and because Linux
    drivers can operate perfectly fine without it (thus without MCQ
    feature).  Linux driver already uses "mcq" as possible name for
    "reg-names" property.

The split allows easier review and maintenance of the binding.
