[PATCH][ARM] Add -mcpu=cortex-a17.cortex-a7

[-- Attachment #1: Type: text/plain, Size: 696 bytes --]

Hi all,

Following up from adding Cortex-A17 support this patch adds a big.LITTLE 
option cortex-a17.cortex-a7.
Similar to the existing cortex-a15.cortex-a7 support we schedule for 
Cortex-A7 and make the other tuning
decisions as for Cortex-A17.

Tested arm-none-eabi.

Ok for trunk?

Thanks,
Kyrill
