ARM: DRA7: Fixup DSP OPP_HIGH clock rate on DRA76P/DRA77P SoCs
The commit 1b42ab3eda8a ("ARM: DRA7: Fixup DSPEVE, IVA and GPU clock frequencies based on OPP") added the core logic to update the kernel device-tree blob to adjust the DSP, IVA and GPU DPLL clocks based on a one-time OPP choice selected in U-Boot for most of the DRA7xx/AM57xx family of SoCs. The DSPs on DRA76xP/DRA77xP SoCs (DRA76x ACD package SoCs) though provide a higher performance and can run at a higher clock frequency of 850 MHz at OPP_HIGH instead of 750 MHz. Fix up the logic to use the correct clock rates on these SoCs. Note that this higher clock rate is not applicable to other Jacinto 6 Plus SoCs (DRA75xP/DRA74xP SoCs or AM574x SoCs) that follow the ABZ package.
