2020b67d85 target-ppc: fix vmx instruction type/type2 
A few of the new instructions added inadvertently changed the type of
old instruction(PPC_ALTIVEC) to PPC2_ALTIVEC_207 in the dual form
declaration.

commit: b5d569a1 (target-ppc: add vector extract instructions)
commit: e7b1e06f (target-ppc: add vector insert instructions)
commit: 3aa56a19 (target-ppc: add vector compare not equal instructions)

New ISA 3.0 instructions added:
    vextractub     PPC_NONE     PPC2_ISA300
    vextractuh     PPC_NONE     PPC2_ISA300
    vextractuw     PPC_NONE     PPC2_ISA300
    vinsertb       PPC_NONE     PPC2_ISA300
    vinserth       PPC_NONE     PPC2_ISA300
    vinsertw       PPC_NONE     PPC2_ISA300
    vcmpneb        PPC_NONE     PPC2_ISA300
    vcmpneh        PPC_NONE     PPC2_ISA300
    vcmpnew        PPC_NONE     PPC2_ISA300

Affected older instructions:
    vspltb         PPC_ALTIVEC  PPC_NONE
    vsplth         PPC_ALTIVEC  PPC_NONE
    vspltw         PPC_ALTIVEC  PPC_NONE
    vspltisb       PPC_ALTIVEC  PPC_NONE
    vspltish       PPC_ALTIVEC  PPC_NONE
    vspltisw       PPC_ALTIVEC  PPC_NONE
    vcmpequb       PPC_ALTIVEC  PPC_NONE
    vcmpequh       PPC_ALTIVEC  PPC_NONE
    vcmpequw       PPC_ALTIVEC  PPC_NONE

Change the instruction type/type2 for the older instructions back to
what it was(PPC_ALTIVEC).
