fsl-lsch2: csu: correct the workaround A-010315

Browse Source 
The implementation of function set_pcie_ns_access() uses a wrong
argument. The structure array ns_dev has a member 'ind' which is
initialized by CSU_CSLX_*. It should use the 'ind' directly to
address the PCIe's CSL register (CSL_base + CSU_CSLX_PCIE*).
