soc/amd/picasso: Add set_mmio_dev_ops() to set ops for MMIO devices
This change adds a helper function set_mmio_dev_ops() in chip.c which
is used for setting the dev->ops for MMIO devices based on the
comparison of MMIO address in device tree to the pre-defined base
addresses in iomap.h.
Call to i2c_acpi_name() is replaced with set_mmio_dev_ops and scope of
i2c_acpi_name is restricted to i2c.c since it is not required to be
exposed out of that file.
