The timer0 node has its two clocks written in reversed order. The timer0
is used as the tick timer which causes a problem that the time a delay
function used is 4 times longer.
This patch reverses these two clocks to solve this issue.

This patch changes mt7629_rfb to use ARM's generic arch timer instead of
MediaTek's soc timer.
