[OE-core] [PATCHv2] Add tune for 32-bit ARMv8-a

[Daniel Dragomir]

This patch adds tunes for 32-bit armv8 platforms. The user can select
the vector floating-point instruction set: vfpv3, vfpv4 or fp-armv8
and the Neon, crc and crypto extensions.

Also, fix some parsing failures for armv7a*-neon-vfpv4 tunes.
