[GCC][PATCH][AArch64] Update hwcap string for fp16fml in aarch64-option-extensions.def 

This is a minor patch that fixes the entry for the fp16fml feature in
GCC's aarch64-option-extensions.def.

As can be seen in the Linux sources here
https://github.com/torvalds/linux/blob/master/arch/arm64/kernel/cpuinfo.c#L69
the correct string is "asimdfhm", not "asimdfml".

Cross-compiled and tested on aarch64-none-linux-gnu.
