[PATCH 3/5] clk: imx8mp: Allow adjusting the video PLL rates for the LDB clock

[Miquel Raynal <miquel.raynal@bootlin.com>]

There must be a x7 or x14 relationship between the LDB clock and the
pixel clocks feeding the LCDIF blocks. There must be some negociation
happening between the two and that may only happen by using the upper
video PLLs. Allow this by setting the CLK_SET_RATE_PARENT flag to the
LDB clock.
