clk: imx6sx: add missing lvds2 clock to the clock tree
i.MX6SX has lvds2 (analog clock2), an I/O clock like lvds1.
And this lvds2, along with lvds1, can be used to provide
external clock source to the internal pll, such as pll4_audio
and pll5_video.
This patch mainly adds the lvds2 to the clock tree and fix its
relationship with pll accordingly.
