sys: convert Linux driver to use generic offset functions

Browse Source 
Strip all slewing code (adjtime(), freq locked nano PLL, fast tick
slewing) from the Linux driver and use the new generic frequency only
slewing instead. The advantages include stable clock control with very
short update intervals, good control of the slewing frequency, cheap
cooking of raw time stamps and unlimited frequency offset.
