Convert the i.MX GPT binding to DT schema format using json-schema.

Signed-off-by: Anson Huang <Anson.Huang@nxp.com>

Changes since V2:
	- in compatible properties, group all the ones with the same
	  fallback to a single 'items' list using enum for the first entry.

-- reg : specifies base physical address and size of the registers.
-- interrupts : should be the gpt interrupt.
-- clocks : the clocks provided by the SoC to drive the timer, must contain
-           an entry for each entry in clock-names.
-- clock-names : must include "ipg" entry first, then "per" entry.

-
-gpt1: timer@10003000 {

-	interrupts = <26>;
-	clocks = <&clks IMX27_CLK_GPT1_IPG_GATE>,
-		 <&clks IMX27_CLK_PER1_GATE>;
