commit fe634a7a9a57fb736e39fb71aa9adc6448a90f94 upstream.
The clock setup on Meson8 cannot achieve a Mali frequency of exactly 182.15MHz. The vendor driver uses "FCLK_DIV7 / 2" for this frequency, which translates to 2550MHz / 7 / 2 = 182142857Hz. 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.
