[patch, MIPS] Update -mvirt option description

[Matthew Fortune <Matthew.Fortune@imgtec.com>]

Hi Catherine,

I'm following up on PR target/80057 to update the description of -mvirt.

I agree with Roland that the description is inconsistent and should not
state 'application specific' as none of the other ASE options include
it. Instead I suggest we put the shortened form of (VZ) in like (XPA)
is shown for -mxpa. The short form of virtualization ASE is usually VZ
not VIRT which has always irritated me about this option name but that
is history.

What do you think?

gcc/
	PR target/80057
	* config/mips/mips.opt (-mvirt): Update description.

Thanks,
Matthew
