Add a SysBus model for the 64 K230 Function IO configuration
registers documented by the K230 Technical Reference Manual.
Preserve the writable configuration fields across aligned 32-bit
accesses, apply the documented reset values, and ignore writes to
read-only and reserved fields. Offsets outside the documented register
list read as zero and ignore writes.
This provides the register behavior used by the Kendryte SDK U-Boot
pinctrl-single driver and Linux IOMUX configuration code.

Instantiate the K230 IOMUX device and map its MMIO region at
0x91105000, replacing the unimplemented device covering the same SoC
address window.
Select the model from the K230 machine configuration and document the
newly modeled device.
