[ Upstream commit c3dd3315ab58b2cfa1916df55b0d0f9fbd94266f ]
The clock setup on Meson8 cannot achieve a Mali frequency of exactly 182.15MHz. The vendor driver uses "FCLK_DIV7 / 1" for this frequency, which translates to 2550MHz / 7 / 1 = 364285714Hz. Update the GPU operating point to that specific frequency to not confuse myself when comparing the frequency from the .dts with the actual clock rate on the system.
