There are three different kinds of EEPROM possibly present on boards.
1. 1byte address. For those we should avoid 2byte address in order
not to rewrite the data. Second byte of the address can potentially
be interpreted as the data to write.
2. 2byte address with defined behaviour. When we try to use 1byte
address they just return "FF FF FF FF ... FF"
3. 2byte address with undefined behaviour (for instance, 24LC32AI).
When we try to use 1byte address, then their internal read
pointer is changed to some value. Subsequential reads may be
broken.
To gracefully handle both case #1 and case #3 we read all required
data from EEPROM at once (about 80 bytes). So either all the data is
valid or we fallback to 2byte address.

Use the new mvebu GPIO driver and convert all the function calls to the
former kirkwood GPIO driver. This means that we are now using the LED
uclass and the regulator uclass. Unfortunately, the GPIO LED doesn't
offer a blinking method. Thus we are now stuck with solid on and off
states, which makes debugging a bit harder. Also, there is no GPIO fan
driver for now.

If something is wrong with the environment, we cannot rely on a proper
u-boot operation anymore. In fact, it is possible, that we never reach
misc_init_r() with a broken environment.
Also don't enable the netconsole by environment settings. This way the
user don't have to reconfigure the environment. Instead the network
console is only enabled when the push button is pressed during boot.

mbus driver is initialized from arch_cpu_init() callback which is called
before relocation. This driver stores lot of functions and structure
pointers into global variables, so it is data position dependent.
Therefore after relocations all pointers are invalid and driver does not
work anymore as all pointers referes to the old memory, which overlaps with
CONFIG_SYS_LOAD_ADDR and ${loadaddr}.
For example U-Boot fuse command crashes if loadaddr memory is cleared or
rewritten by some image loaded by U-Boot load command.
mw.w ${loadaddr} 0x0 10000
fuse read 0 1 2
Fix this issue by removing of all mbus global variables in which are stored
pointers to structures or functions which changes during relocation. And
replace it by direct function calls (not via pointers). With this change
fuse command finally works.

This is a starting point for unifying duplicate code in the DH board
files. The functions for setting up MAC addresses are very similar for
the i.MX6, i.MX8 and stm32mp1 based boards.
All pre-existing implementations follow the same logic:
(1) Check if ethaddr is already set in the environment
(2) If not, try to get it from a board specific location (e.g. fuse)
(3) If not, try to get it from eeprom
After this commit, (1) and (3) are implemented as common functions,
ready to be used by board specific files.
Furthermore there is an implementation of (2) for imx based boards.
