timer: orion-timer: Fix problem in early_init_done()

It was noticed that Clearfog is currently broken with this newly
introduced early_init_done() function. Apparently the timer is enabled
here when U-Boot is run but not configured - at least not correctly.
Resulting in a hangup in the timer reading functions.

To fix this, also read the value of the reload register and check it's
value with the one written to by U-Boot. Only if this matches, the
init has already been done.
