ARC: Fix iteration in arc_xx_version()

"i" gets incremented before we're entering loop body
and effectively we iterate from 1 to 8 instead of 0 to 7.

This way we:
a) Skip the first line of struct

ARC: Fix iteration in arc_xx_version()

"i" gets incremented before we're entering loop body
and effectively we iterate from 1 to 8 instead of 0 to 7.

This way we:
a) Skip the first line of struct hs_versions
b) Go over it and access memory beyond the structure

ARC: Improve identification of ARC cores

1. Try to guess a ARC core template that was used
i.e. not just name a core family but something more
menaingful like "ARC HS38", "ARC EM11D" etc.

We do it checking availability of the key differentiation
features like:
- Caches (we actually only check for L1 I$ fpr simplicity)
- XY-memory
- DSP extensions etc.

2. Identify ARC subsystems

3. Print core clock frequency

ARC: make generic print_cpuinfo() weak

This allows board to override print_cpuinfo() because
they might know better which ARChitect template was used.
This way we may not only derive base architectu

ARC: make generic print_cpuinfo() weak

This allows board to override print_cpuinfo() because
they might know better which ARChitect template was used.
This way we may not only derive base architecture type and
version but more meaningful things like "ARC EM7D" instead of
simple "ARC EM", "ARC HS36" instead of "ARC HS".
