Subject: [PATCH v2 0/3] clk: xgene: Add PMD clock support

Add X-Gene PMD clock support.

PMD clock is implemented for a single register field.
  Output rate = parent_rate * (denominator - scale) / denominator
with
  - denominator = bitmask of register field + 1
  - scale = value of register field

For example, for bitmask is 0x7, denominator will be 8 and scale
will be computed and programmed accordingly.

v2
 * Imply clock shift and width by the compatible string as Rob's comments

v1
 * Initial
