nios2: Replace strcpy() with strscpy() and simplify setup_cpuinfo()

Browse Source 
strcpy() is deprecated; use strscpy() instead.

Since the destination buffer has a fixed length, strscpy() automatically
determines its size using sizeof() when the size argument is omitted.
This makes the explicit size argument unnecessary - remove it.

Now, combine both if-else branches using strscpy() and the same buffer
into a single statement to simplify the code.

No functional changes intended.
