pinctrl: zynq: fix typo in group name for qspi1

Due to a typo Zynq pin controller does not set pin function of qspi1
when using function qspi1. So pin group for qspi1 has to be renamed to
"qspi1_0_grp" as outlined in the corresponding bindings documentation.

This also removes kernel message:
  zynq-pinctrl 700.pinctrl: invalid group "qspi1_0_grp" for function "qspi1"
