	When the interrupt property fails to be parsed, ep93xx_timer_of_init() return code ends up uninitialized: drivers/clocksource/timer-ep93xx.c:160:6: error: variable 'ret' is used uninitialized whenever 'if' condition is true [-Werror,-Wsometimes-uninitialized] if (irq < 0) { ^~~~~~~ drivers/clocksource/timer-ep93xx.c:188:9: note: uninitialized use occurs here return ret; ^~~ drivers/clocksource/timer-ep93xx.c:160:2: note: remove the 'if' if its condition is always false if (irq < 0) { ^~~~~~~~~~~~~~ Simplify this portion to use the normal construct of just checking whether a valid interrupt was returned. Note that irq_of_parse_and_map() never returns a negative value and no other callers check for that either.

	Rewrite EP93xx timer driver located in arch/arm/mach-ep93xx/timer-ep93xx.c trying to do everything the device tree way: - Make every IO-access relative to a base address and dynamic so we can do a dynamic ioremap and get going. - Find register range and interrupt from the device tree.
