SPARC: Emulation of GRLIB GPTimer

Browse source 
This device exposes three parameters:
 - frequency (uint32) : The system frequency
 - irq-line  (uint32) : IRQ line number for the first timer
                        (others use irq-line + 1, irq-line + 2...)
 - nr-timers (uint32) : Number of timers

Emulation of GrLib devices is base on the GRLIB IP Core User's Manual:
