    [PATCH/AARCH64] Add ThunderX T88 pass1 -mpcu option
    
    Hi,
      ThunderX T88 pass 1.x does not include ARMv8.1 support but all future ThunderX (including T88 pass 2) does so we need an option to distinguish the two.  Note ThunderX is family of processors and they all have very similar cores (just errata fixes) which have different part numbers so having a different -mcpu= for each of those processors does not make sense.
    
    ok?  Build and tested on aarch64-linux-gnu with no regressions.
    
    ChangeLog:
    	* config/tc-aarch64.c (aarch64_cpus):
    	Add thunderxt88pass1.
    	* doc/c-aarch64.texi: Document that thunderxt88pass1
    	is a valid processor name.
