ARM: dts: meson8: add the Mali-450 MP6 GPU
Add the Mali-450 GPU and it's OPP table for the Meson8 and Meson8m2 (the
latter inherits meson8.dtsi).
These SoCs have a Mali-450 GPU with six pixel processors. The OPP table
is taken from the 3.10 vendor kernel which uses the following table:
FCLK_DEV7 | 1, /* 182.1 Mhz */
FCLK_DEV4 | 1, /* 318.7 Mhz */
FCLK_DEV3 | 1, /* 425 Mhz */
FCLK_DEV5 | 0, /* 510 Mhz */
FCLK_DEV4 | 0, /* 637.5 Mhz */
This describes the mux (FCLK_DEVx) and a 0-based divider in the clock
controller. "FCLK" is "fixed_pll" which is running at 2550MHz.
The "turbo" setting is described by "turbo_clock = 4" where 4 is the
index of the table above.
