p9_sbe_npll_setup: Enable Spread Spectrum right after SS PLL lock

2017-12-12T03:54:06+00:00

As it is no longer a requirement that Spread Spectrum is enabled on all SS PLLs in a system in unison, we're better off turning on spreading as early as possible, so any link training runs off of a spread clock. The only way to enable Spread Spectrum in P9 is via the TOD Timer, so we have to set up a timer compare value of 1 and force the TOD value to 1 so that the timer is hit and the TOD's spread enable output turns on.
