mlx-platform does not provide a bus number to i2c-mlxcpld, assuming it is always one. On some x86 systems, other i2c drivers may probe before i2c-mlxcpld, causing bus one to be busy. Make mlx-platform determine which adapter number is free prior to activating i2c-mlxpld, adjusting the mux base numbers accordingly. Update the mlxreg-hotplug pdata similarly. This adds an explicit mlx-platform build dependency on I2C, update the Kconfig accordingly. Add the missing REGMAP dependency while we're at it.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
