We currently select CONFIG_V7M for a bunch of our m-profile devices.
The last sticking point is translate.c which cannot be compiled
without expecting v7m support. Express this dependency in Kconfig
rather than in default devices as a stepping stone to a fully
configurable translate.c.

While we are at it we also need to select ARM_COMPATIBLE_SEMIHOSTING
as that is implied for M profile machines.
