zynq: nand: do not wait on erase completion in cmd_func

The chip command function dont have to wait on ERASE completion
as the dev_ready chip function is defined and use of the default
nand_erase is made.

This fixes the "Timeout!" error while doing "nand erase" and
also the very low NAND erase performace.
