[PATCH kernel v2] powerpc/powernv: Fix debug macro

[Alexey Kardashevskiy]

When cfg_dbg() is enabled (i.e. mapped to printk()), gcc produces
errors as the __func__ parameter is missing (pnv_pci_cfg_read() has one);
this adds the missing parameter. Since cfg_dbg() is used not just for
config space access, this replaces it with well-known pr_devel().
