Currently when CONFIG_POWERNV is not enabled, the build fails, such as
with --without-default-devices:
$ ./configure --without-default-devices
$ make

This is since target/ppc/misc_helper.c references PowerNV specific
'pnv_chip_find_core' call.
Split the PowerNV specific SPRD code out of the generic PowerPC code, by
moving the SPRD code to pnv.c
