On K3 Pico-ITX the GMAC RGMII group lists pin 0 as\nits first entry, so its drive-strength / bias configuration was silently\nignored.\n\nThe intended guard is against spacemit_get_pin() returning NULL when the\npin id isn't in the SoC's pin table. Check spin instead, which both\nrestores PAD setup for pin 0 and prevents a NULL deref on spin->pin."
