net: zynq: Add missing const to wait_for_bit()

Remove compilation warning:
../drivers/net/zynq_gem.c:407:19: note: expected 'char *' but argument
is of type 'const char *'
../drivers/net/zynq_gem.c:476:8: warning: passing argument 1 of
'wait_for_bit' discards 'const' qualifier from pointer target type
[enabled by default]
