Mikael Pettersson 980f2296b5 iop: enable generic time 
This updates the IOP platform to use the kernel's generic time
framework. With clockevent support in place, this reduces to
selecting GENERIC_TIME and removing the platform's private timer
->offset() operation (iop_gettimeoffset).

Tested on n2100, compile-tested for all plat-iop machines.
