Subject: clk: mediatek: add the option for determining PLL source clock

From: Chen Zhong <chen.zhong@mediatek.com>


[ Upstream commit c955bf3998efa3355790a4d8c82874582f1bc727 ]

Since the previous setup always sets the PLL using crystal 26MHz, this
doesn't always happen in every MediaTek platform. So the patch added
flexibility for assigning extra member for determining the PLL source
clock.
