ARM: dts: msm: Add necessary changes for CQE enablement on sdxlemur

Add necessary changes for CQE enablement:

1) Add gpio based data lines (DAT[4:7]) to pinctrl file
2) Set VI recommended drive strength values for clk, cmd and data lines
3) Add clk scaling device tree support
4) Add CQE device tree flag.
