clk: qoriq: avoid format string warning

clang-22 warns about the use of non-variadic format arguments passed into
snprintf():

drivers/clk/clk-qoriq.c:925:39: error: diagnostic behavior may be improved by adding the
      'format(printf, 7, 8)' attribute to the declaration of 'create_mux_common' [-Werror,-Wmissing-format-attribute]

Rework this to pass the 'int idx' as a varargs argument, allowing the
format string to be verified at the caller location.
