Subject: [PATCH V2 0/2] phy: xilinx: phy-zynqmp: dynamic clock support

This patch of the series adds the following supports:
- Runtime PM support:
  Added runtime power management support to power saving during the
  suspend and resume calls.

- Dynamic clock support:
  Current zynqmp-phy driver, by default all the clock enabled for all
  the lanes, that consumes power even PHY is active or idle.
  So, the dynamic clock feature will be enabled clock only for active
  PHY in the phy_init and disabled in phy_exit. Clock enabling is not
  required at multiple times. Activation of PHY depends on the peripheral
  DT node status (status = "okay";).

Changes in V2:
- Addressed Vinod Koul review comments:
 - Added runtime PM support - "DEFINE_RUNTIME_DEV_PM_OPS" MACRO used.
 - Updated commit message for dynamic clock support.
