dts: riscv: spacemit: k3: Fix I/O power settings

Browse Source 
SpacemiT K3 SoC support dual-voltage I/O power domain, while initially
configure to 3.3v, and need to access register from APBC space to switch
to 1.8v domain.

Fix the GMAC0's I/O pins 1.8v switch failure that will result a broken
ethernet driver.
