Convert the Lantiq SoC ASC UART binding to DT schema. There are no such
clock identifier defines nor a user with clocks, so drop the example
with clocks.

-Lantiq SoC ASC serial controller
-
-Required properties:
-- compatible : Should be "lantiq,asc"
-- reg : Address and length of the register set for the device
-- interrupts: the 3 (tx rx err) interrupt numbers. The interrupt specifier
-  depends on the interrupt-parent interrupt controller.
-
-Optional properties:
-- clocks: Should contain frequency clock and gate clock
-- clock-names: Should be "freq" and "asc"
-
-Example:
-
-asc0: serial@16600000 {
-	compatible = "lantiq,asc";
-	reg = <0x16600000 0x100000>;
-	interrupt-parent = <&gic>;
-	interrupts = <GIC_SHARED 103 IRQ_TYPE_LEVEL_HIGH>,
-		<GIC_SHARED 105 IRQ_TYPE_LEVEL_HIGH>,
-		<GIC_SHARED 106 IRQ_TYPE_LEVEL_HIGH>;
-	clocks = <&cgu CLK_SSX4>, <&cgu GCLK_UART>;
-	clock-names = "freq", "asc";
-};
-
-asc1: serial@e100c00 {
-	compatible = "lantiq,asc";
-	reg = <0xE100C00 0x400>;
-	interrupt-parent = <&icu0>;
-	interrupts = <112 113 114>;
-};
