sim: m32r: migrate from WITH_DEVICES to WITH_HW The m32r port was using the device framework to handle two devices: the cache and uart registers. Both can be implemented in the newer hardware framework instead which allows us to drop the device logic entirely, as well as delete the tconfig.h file. While creating the new uart device model, I also added support for using stdin to read/write data rather than only supporting sockets. This has been lightly tested as there doesn't appear to be test coverage for the code already. If anyone still cares about this port, then they should (hopefully) file bug reports.

/* UART model.
Update copyright year range in all GDB files. This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.
