[OE-core] [v2][PATCH 2/2] goarch.bbclass: set TARGET_GOARM as '7' for valid cortexa* targets

[Mark Asselstine]

Per https://github.com/golang/go/wiki/GoArm we need to set GOARM when
building for ARMv5, ARMv6 and ARMv7. The current code in go_map_arm()
does not account for the Cortex* TUNINGs and as such misses several
Cortex variants which implement ARMv7. Here we add an additional check
that will include Cortex-A5 through Cortex-A17 as ARMv7 variants
(ie. GOARM='7'). The Cortex-R and Cortex-M variants are also captured
even though there are no tunings for these currently (lack MMU support
so not supported).
