This uses the standard blankings but a slightly slower clock rate, thus getting a refresh rate 58.3 Hz. NOTE: this won't really do anything except cause DRM to properly report the refresh rate since vop_crtc_mode_fixup() was rounding the pixel clock to 74.25 MHz anyway. Apparently the adjusted rate isn't exposed to userspace so it's important that the rate we're trying to achieve is mostly right. For the downstream kernel change related to this see See https://crrev.com/c/324558. NOTE: minnie uses a different panel will be fixed up in a future patch, so for now we'll just delete the panel timings there.
