Spurious mtk timer interrupt is noticed at boot and cause kernel

spurious interrupt.
Change init flow to only enable GPT_CLK_SRC at mtk_timer_init.

Update to my patch [1], added __init as Daniel suggest. This is the
only patch that need to change in that series, so I only sent this one.

Hi Daniel, Thomas,

Any suggestions for mtk_timer fixes in this series?
Should I resend and add tags from the reviewers?
