Neil Armstrong b2037dafcf arm64: dts: meson-gxl-s805x: reduce initial Mali450 core frequency
When starting at 744MHz, the Mali 450 core crashes on S805X based boards:
 lima d00c0000.gpu: IRQ ppmmu3 not found
 lima d00c0000.gpu: IRQ ppmmu4 not found
 lima d00c0000.gpu: IRQ ppmmu5 not found
 lima d00c0000.gpu: IRQ ppmmu6 not found
 lima d00c0000.gpu: IRQ ppmmu7 not found
 Internal error: synchronous external abort: 96000210 [#1] PREEMPT SMP

 Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b

Reverting to a safer 666Mhz frequency on the S805X that doesn't use the
GP0 PLL makes it more stable.
