tty: ar933x_uart: move devicetree binding documentation

Commit 'tty: ar933x_uart: add device tree support
and binding documentation' introduced a new doc in
bindins/tty/serial.

According to a recent thread [1] on the linux-serial
list, the binding documentation of serial drivers
should be added into bindings/serial.

Move the documentation of qca,ar9330-uart to the
correct place.

+* Qualcomm Atheros AR9330 High-Speed UART
+
+Required properties:
+
+- compatible: Must be "qca,ar9330-uart"
+
+- reg: Specifies the physical base address of the controller and
+  the length of the memory mapped region.
+
+- interrupt-parent: The phandle for the interrupt controller that
+  services interrupts for this device.
+
+- interrupts: Specifies the interrupt source of the parent interrupt
+  controller. The format of the interrupt specifier depends on the
+  parent interrupt controller.
+
+Additional requirements:
+
+  Each UART port must have an alias correctly numbered in "aliases"
+  node.
+
+Example:
+
+       aliases {
+               serial0 = &uart0;
+       };
+
+       uart0: uart@18020000 {

+               reg = <0x18020000 0x14>;

+               interrupt-parent = <&intc>;
