[arm] Use neon_dot_q type for 128-bit V[US]DOT instructions where appropriate
For the Dot Product instructions we have the scheduling types neon_dot and neon_dot_q for the 128-bit versions.
It seems that we're only using the former though, not assigning the neon_dot_q type anywhere.
This patch fixes that by adding the <q> mode attribute suffix to the type, similar to how we do it for other
types in neon.md.
* config/arm/neon.md (neon_<sup>dot<vsi2qi>):
Use neon_dot<q> for type.
(neon_<sup>dot_lane<vsi2qi>): Likewise.
