Improve handling of call insns in cortex-a7 pipeline description, as
follows.

A call can dual-issue as a younger instruction but not as an older
instruction (from compiler's point of view). This patch adjusts the function
cortexa7_younger (used by the implementation of TARGET_SCHED_REORDER hook)
to return true for calls. The patch also updates the pipeline description
for calls to allow either dual-issue as a younger instruction or
single-issue.

         * config/arm/arm.c (cortexa7_younger): Return true for TYPE_CALL.
         * config/arm/cortex-a7.md (cortex_a7_call): Update required units.

Ok.
