usb: fotg210: Collect pieces of dual mode controller The Faraday FOTG210 is a dual-mode OTG USB controller that can act as host, peripheral or both. To be able to probe from one hardware description and to follow the pattern of other dual- mode controllers such as MUSB or MTU3 we need to collect the two, currently completely separate drivers in the same directory. After this, users need to select the main symbol USB_FOTG210 and then each respective subdriver. We pave the road to compile both drivers into the same kernel and select the one we want to use at probe() time, and possibly add OTG support in the end. This patch doesn't do much more than create the new symbol and collect the drivers in one place. We also add a comment for the section of dual-mode controllers in the Kconfig file so people can see what these selections are about. Also add myself as maintainer as there has been little response on my patches to these drivers.

usb: fotg210: Compile into one module It is since ages perfectly possible to compile both of these modules into the same kernel, which makes no sense since it is one piece of hardware. Compile one module named "fotg210.ko" for both HCD and UDC drivers by collecting the init calls into a fotg210-core.c file and start to centralize things handling one and the same piece of hardware. Stub out the initcalls if one or the other part of the driver was not selected. Tested by compiling one or the other or both of the drivers into the kernel and as modules.

usb: fotg210: Use -y instead of -objs in Makefile -objs suffix is reserved rather for (user-space) host programs while usually -y suffix is used for kernel drivers (although -objs works for that purpose for now). Let's correct the old usages of -objs in Makefiles.
