arch/arm: add big.LITTLE cpu variants
The big.LITTLE configurations can be optimised for by gcc, and a few
users wonder what they should choose when they have such CPUs.
Add new entries for those big.LITTLE configurations.
Note: the various combos were added in various gcc versions, but only
really worked in later versions:
Variant | Introduced in | First built in
----------+---------------+----------------
a15-a7 | 4.9 | 4.9
a17-a7 | 5 | 5
a57-a53 | 4.9 | 6
a72-a53 | 5 | 6
