PCI: hisi: Fix hisi_pcie_cfg_read() 32-bit reads
For 32-bit config reads (size == 4), hisi_pcie_cfg_read() returned success
but never filled in the data we read.
Return the register data for 32-bit config reads.
Without this fix, PCI doesn't work at all because enumeration depends on
32-bit config reads. The driver was tested internally, but got broken in
the process of upstreaming, so this fixes the breakage.
