[U-Boot] [PATCH 1/3] arm: dts: MediaTek: fix clock order for timer0 node of mt7629.dtsi
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.

Applied to u-boot/master, thanks!
This patch removes tick-timer as all mt7629 boards should use arch timer.
