The crash http://termbin.com/zitb is caused by the timer register
into system in early pahse during kernel boot, but the clock
sources didn't get ready at that time.
A better way is to switch to use CLK_OF_DECLARE() in driver for things
that need them early, but this node is actually useless in MT7622.
So we drop it.
