As of 0.9.9b, the ddbridge code has been split from one single file
(ddbridge-core.c) into multiple files, with the purpose of taking care of
different topics, and to be able to reuse code in different kernel modules
(ddbridge.ko and octonet.ko). This applies the same code split, with a
notable difference:
In the vendor package, the split was done by moving all code parts into
separate files, and in the "main" code files (ddbridge.c and octonet.c),
a simple "#include ddbridge-core.c" was done.
In this patch, the same split (codewise) is done, but all resulting .c/.o
files will be handled by the makefile, with proper prototyping of all
shared functions done in ddbridge.h. To avoid conflicts wrt the global
space, the I2C functions and necessary prototypes for ddbridge-i2c.c are
moved into ddbridge-i2c.h, which is to be included wherever required.

The .data and .bss sections were modified in the generic linker script to
pull in sections named .data.<C identifier>, which are generated by gcc with
-ffunction-sections and -fdata-sections options.
The problem with this pattern is it can also match section names that Linux
defines explicitly, e.g., .data.unlikely. This can cause Linux sections to
get moved into the wrong place.
The way to avoid this is to use ".." separators for explicit section names
(the dot character is valid in a section name but not a C identifier).
However currently there are sections which don't follow this rule, so for
now just disable the wild card by default.

But instead it will only return -ENODEV when there are no supplies at

then only when __power_supply_is_supplied_by returns true. This commit
