[PATCH] m68k: atari: Use strscpy() in atari_switches_setup()

[Thorsten Blum <blum@kernel.org>]

strcpy() has been deprecated [1] because it performs no bounds checking
on the destination buffer, which can lead to buffer overflows.

While the current code works correctly, replace strcpy() with strscpy()
to bound the copy to the size of the switches buffer.
