* Implemented driver for MCP23017
* fixed compatability with mcp23009. (naming of instantiated GPIO-Devices)
* removed some comments
* removed even more comments
* commented out instatntiation of driver since it will not be used with v6x
* removed last useless comments
* re-activated gpio_mcp23009 driver, removed useless comments and empty lines
* removed empty lines at the end of mcp23017.cpp
* removed empty line

* re-activated gpio_mcp23009 driver, removed useless comments and empty lines
* removed empty lines at the end of mcp23017.cpp
* removed empty line
* basic working implementation
* first improved driver version with shared code base for MCP23009 & MCP23017 (built as state machine with sanity checks)
* removed unused imports
* changed module name from MCP to MCP230XX
* removed debug print statements
* adjusted auto start command of driver
* removed comments
* -added seperate main functions for both derivative modules (mcp23009 and mcp23017)
* compile common functions as shared library in src/lib/drivers
* fixed cleanup of modules
* ->unclean working version with shared common library
* used make format
* working & cleaned version
* -> Added CallbackHandler to be able to use multiple reading GPIO-expanders simultaneously
-> Removed old mcap23009 calls and pin registrations
-> Adjusted GpioIn.msg to contain MAX_INSTANCES
* ->removed unused imports
->used make format
* Fix: Re-enabled platform_mcp_gpio for accton-godwit, cuav, fmu-v5x
* Fix: enabled platform_mcp_gpio in px4/fmu-v5x
* added depency to fmu-v5x
* Fix: removed new lines
* Fix: fixed linker errors
* removed unused linkage against mcp-library
* Made mcp start calls consistent for fmu-v5x and fmu-v6x
* moved logging of comm errors to read/write function directly
* added perf_count for sanity_check
* removed error message
* ensured member variables follow naming convention
* added retries to probe function
* simplyfied state-logic
* add break to terminate loop early
* ensured clean state when register_gpios() fails
* add registered-flag to pins
* used path from top dir instead of relative path in CMakeLists
* used constexpr to set parameters instead of calculating them at runtime
* style: used make format
* fix: corrected i2c_bus assignment
* style: init input of callbackhandler to 0
* fix: mark pin as registered if successful
* style: made arguments const type

The param is not really required anymore with the actuator
configuration. Also, when it is set to 0, RC doesn't work for some
boards which would be nice to avoid.
