We store a SW state of the t11_t12 timing in 100usec units but have to
program it in 100msec as required by HW. The rounding used during
programming means there will be a mismatch between the SW and HW states
of this value triggering a "PPS state mismatch" error. Avoid this by
storing the already rounded-up value in the SW state.
Note that we still calculate panel_power_cycle_delay with the finer
100usec granularity to avoid any needless waits using that version of
the delay.

As a micro-optimization I guess we might want to move the division here
as well. But maybe that would cause more confusion since all the other
timings are in 100usec units. Dunno.

Yep, had v1 like that with the same dilemma. In any case that could be
done separately imo to keep this minimal in case someone wants to
backport it.
