microblaze: Fix CONFIG_SYS_HZ usage in board config
Do not use hardcoded value. Use CONFIG_SYS_HZ instead. Separate static configuration to single block.

- } else {
for (i = 0; i< (usec * XILINX_CLOCK_FREQ / 10000000); i++);this part should be enclosed by #ifdef XILINX_CLOCK_FREQ
It was intentional because XILINX_CLOCK_FREQ must be define. Maybe it could be handle by
#ifndef XILINX_CLOCK_FREQ # error Please define XILINX_CLOCK_FREQ #endif
Thanks, Michal
