For boards who run their SoC at a higher voltage than nominal,
the boards can run several clocks at an overdrive rate for
better performance.  Add an optional DTSI file which can be
included by various boards to run in overdrive mode.

This raises the GPU PLL to 1000MHz, and the VPU PLL to
700MHz while moving VPU_G1 and VPU_H1 to the SYS_PLL3_OUT
which runs at 750MHz.

When the GPU nodes were added, the GPU_PLL_OUT was configured
for 1000MHz, but this requires the SoC to run in overdrive mode
which requires an elevated voltage operating point.

Since this may run some boards out of spec, the default clock
should be set to 800MHz for nominal operating mode. Boards
that run at the higher voltage can update their clocks
accordingly.

Since commit 8208181f ("clk: imx: composite-8m:
Add imx8m_divider_determine_rate") the lcdif controller has
had the ability to set the lcdif_pixel rate which propagates
up the tree and sets the video_pll1 rate automatically.

By setting this value low, it will force the recalculation of
video_pll1 to the lowest rate needed by lcdif instead of
dividing a larger clock down to the desired clock speed. This
has the  advantage of being able to lower the video_pll1 rate
from 594MHz to 148.5MHz when operating at 1080p. It can go even
lower when operating at lower resolutions and refresh rates.

The device tree clock structure for the mipi_dsi is
unnecessarily redundant.

The default clock parent of IMX8MM_CLK_DSI_PHY_REF is
already IMX8MM_CLK_24M, so there is no need to set the
parent-child relationship between them.  The default clock
rates for IMX8MM_SYS_PLL1_266M and IMX8MM_CLK_24M are
already defined to be 266MHz and 24MHz respectively,
so there is no need to define those clock rates.

On i.MX8M[MNP] the  samsung,pll-clock-frequency is not
necessary, because the driver will read it from sclk_mipi
which is also already set to 24MHz making it also
redundant.
