[PATCH v2 01/11] clk: imx8mp: add 700 MHz rate entry for VIDEO_PLL1

[Johannes Schneider]

From: Thomas Haemmerle <thomas.haemmerle at leica-geosystems.com>

LVDS link_freq = pixel_clock * 7.  For a 25 MHz pixel clock that's
175 MHz, requiring VIDEO_PLL1 at 700 MHz so the /4 divider yields an
exact match.  Without the table entry, clk_set_rate() rounds down to
650 MHz (giving 162.5 MHz) and the LVDS transmitter outputs ~743
pixels per 800-pixel line.

PLL parameters: Fin=24 MHz, P=3, S=2, K=0 -> 24 * 350 / (3 * 4) = 700 MHz.
