misc: keba: Add UART devices
Add support for the UART auxiliary devices. This enables access to up to
3 different UARTs, which are implemented in the FPGA.

misc: keba: Support EEPROM sections as separate devices
The main EEPROM of KEBA CP500 devices is divided into two sections. One
section for type label data like device name, order number, serial
number and so on. The second section is reserved for arbitrary data
stored by the user.
The two sections have a defined range. The first 3 kB for the type label
and the remaining 1 kB for user data. The type label is written during
production and can fill up the whole 3 kB. Thus, the range is fixed and
cannot be changed dynamically.
The two sections cannot be presented as NVMEM cells. A NVMEM cell is
always read and written at once, because the data presented to the user
can differ from the data stored in the physical NVMEM cell. Thus, NVMEM
cells would lead to reading 3 kB for every type label access, even if
only the device name is read. So performance would suffer. But it is
also an indication that NVMEM cells are designed for small data cells
within NVMEM devices.
Register separate NVMEM devices for every section. This enables safe
access to every section. Also different access rights are then possible.

misc: keba: Add LAN9252 driver
KEBA CP500 devices use the LAN9252 controller for EtherCAT
communication. For a stable Ethernet link the PHY registers of the
controller need to be configured correctly. This driver configures these
PHY registers as required.
