ARM: OMAP: Don't store timers physical address
The OMAP2+ system timer code stores the physical address of the timer but never uses it. Remove this and clean-up the code by removing the local variable "size" and changing the names of the local variables mem_rsrc and irq_rsrc to mem and irq, respectively.
