The ACPI companion of the adapter has to be set for I2C controller
code to read and attach the slave devices described in the ACPI table
with the I2CSerialBus resource descriptor. Used ACPI_COMPANION_SET
macro to set this.

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.
Export the module alias information using the MODULE_DEVICE_TABLE() macro.

Added ACPI support for the I2C controller present on Broadcom's
Vulcan ARM64 processor. ACPI ID used by the controller is BRCM9007.
Changed the xlp9xx_i2c_get_frequency() function to use
device_property_read_u32() API so that the "clock-frequency" value
can be read from _DSD in ACPI mode.

Add an I2C bus driver i2c-xlp9xx.c to support the I2C block in the
XLP9xx/XLP5xx MIPS SoC. Update Kconfig and Makefile to add the
CONFIG_I2C_XLP9XX option.
