Candera/FeatStd CMake Build System Changes

i.MX6 Custom Driver Includes

With the newest board support packages the drivers are available together with the other includes and libraries required when cross-compiling for the i.MX6. Therefore, it is now no longer required to specify custom driver include and library paths. The CGIDEVICE_CUSTOM_PATHS CMake parameter has been removed, together with the CGIDEVICE_TARGET_IMX6_DRIVER_PATH_INCLUDE and CGIDEVICE_TARGET_IMX6_DRIVER_PATH_LIB parameters. Ensure that the driver includes and libraries are available in the sysroot specified for cross-compilation.
