[PATCH,ARM][5/5] Cleanup in cortex-a7 pipeline description

[Greta Yorsh]

In cortex_a7_idiv, the use of cortex_a7_all reservation can be replaced by
cortex_a7_both, because all other reservations require at least one of
cortex_a7_ex1 or cortex_a7_ex2. Then, remove unused reservation units
cortex_a7_neon and cortex_a7_all.

        * config/arm/cortex-a7.md (cortex_a7_neon, cortex_a7_all): Remove.
        (cortex_a7_idiv): Use cortex_a7_both instead of cortex_a7_all.
