net: thunderx: Rewrite silicon revision tests.
The test for pass-1 silicon was incorrect, it should be for all
revisions less than 8. Also the revision is already present in the
pci_dev, so there is no need to read and keep a private copy.
Remove rev_id and code to read it from struct nicpf. Create new
static inline function pass1_silicon() to be used to testing the
silicon version. Use pass1_silicon() for revision checks, this will
be more widely used in follow on patches.
