rs6000: Harden mma_init_builtins

The previous MMA patch added some fragile code to initialize its new
built-ins.  This patch hardens the initialization.

2021-07-07  Peter Bergner  <bergner@linux.ibm.com>

gcc/
	* config/rs6000/rs6000-call.c (mma_init_builtins): Use VSX_BUILTIN_LXVP
	and VSX_BUILTIN_STXVP.
