[PATCH AUTOSEL 4.19 10/13] MIPS: Restore Au1300 support

[ Upstream commit f2041708dee30a3425f680265c337acd28293782 ]

The Au1300, at least the one I have to test, uses the NetLogic vendor
ID, but commit 95b8a5e0111a ("MIPS: Remove NETLOGIC support") also
dropped Au1300 detection. Restore Au1300 detection.

Tested on DB1300 with Au1380 chip.
