arm64: zynqmp: Get rid of simple_itoa and replace it by snprintf

Browse Source 
simple_itoa() is implemented only for !CONFIG_USE_TINY_PRINTF. Tiny printf
is normally used by SPL that's code which uses simple_itoa() has missing
reference. That's why refactor code by using on snprintf() instead of
strncpy()/strncat() combination. This change also descrease code size by
saving 24B based on buildman.
