[PATCH 1/2] clk: rockchip: rk3399: add 85.5 MHz rate to PLL rate table

[Vasily Khoruzhick <anarsoul@gmail.com>]

85.5 MHz is the pixel clock of the standard DMT 1366x768@60 mode,
which is the native mode of many cheap HDMI panels.

Use a 1368 MHz VCO (24 MHz * 57, already used by the existing
1368 MHz entry) with postdiv1 = postdiv2 = 4 to hit 85.5 MHz
exactly in integer mode.
