[v1 1/2] sparc64: use prom interface to get %stick frequency

[Pavel Tatashin <pasha.tatashin@xxxxxxxxxx>]

We initialize time early, we must use prom interface instead of open
firmware driver, which is not yet initialized.

Also, use prom_getintdefault() instead of prom_getint() to be compatible
with the code before early boot timestamps project.
