nios2: Replace all non-returning strlcpy with strscpy strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). No return values were used, so direct replacement is safe.

nios2: get cpu node with of_get_cpu_node "device_type" use is deprecated for FDT though it has continued to be used for nodes like cpu nodes. Use of_get_cpu_node() instead which works using node names by default. This will allow the eventually removal of cpu device_type properties. Also, fix a leaked reference by adding a missing of_node_put. Cc: Ley Foon Tan <lftan@altera.com> Cc: nios2-dev@lists.rocketboards.org Signed-off-by: Rob Herring <robh@kernel.org>

nios2: Add NIOS2_ARCH_REVISION to select between R1 and R2 Allow user to select between Nios2 R1 and R2. Since R1 and R2 are not binary compatible, we cannot have a single kernel binary and there is no point in having DT property for discerning these two.
