freedreno/decode: Lookup device info

First step for migration to chip_id.  With newer devices we won't be
able to decode the chip_id in any meaningful way, ie. it is just a
number.  But we can use the device table to figure out things like
generation which are needed to properly decode cmdstream, etc.
