32-bit timers. The S900 SoC timer block has four 32-bit timers.

Signed-off-by: Andreas Färber <afaerber@...e.de>

 v2 -> v3:
 * Adopted interrupt-names
 * Changed compatible for S500
 * Added S900 compatible and interrupt names
 
 v2: new

+Actions Semi Owl Timer
+
+Required properties:
+- compatible      :  "actions,s500-timer" for S500
+                     "actions,s900-timer" for S900
+- reg             :  Offset and length of the register set for the device.
+- interrupts      :  Should contain the interrupts.
+- interrupt-names :  Valid names are: "2Hz0", "2Hz1",
+                                      "Timer0", "Timer1", "Timer2", "Timer3"
+                     See ../resource-names.txt
+
+Example:
+
+		timer@...68000 {
+			compatible = "actions,s500-timer";
+			reg = <0xb0168000 0x100>;
+			interrupts = <GIC_SPI 10 IRQ_TYPE_LEVEL_HIGH>,
+			             <GIC_SPI 11 IRQ_TYPE_LEVEL_HIGH>;
+			interrupt-names = "Timer0", "Timer1";
