dt-bindings: net: nxp,s32-dwmac: Use the GPR syscon

This commit adds the nxp,phy-sel property to the S32 DWMAC binding,
allowing access to the GMAC_0_CTRL_STS register via a syscon interface
instead of the previous ad-hoc direct register mapping.

Should this be GMAC_0 (with a zero) instead of GMAC_O (with a letter O)?
The rest of the description uses GMAC_0_CTRL_STS and GMAC_0 consistently.
