target/riscv/cpu_helper: Fix linking problem with semihosting disabled

If QEMU has been configured with "--without-default-devices", the build
is currently failing with:

/usr/bin/ld: libqemu-riscv32-softmmu.a.p/target_riscv_cpu_helper.c.o:

reference to `do_common_semihosting'

We always want semihosting to be enabled if TCG is available, so change
the "imply" statements in the Kconfig file to "select", and make sure to
avoid calling into do_common_semihosting() if TCG is not available.

kconfig: express dependency of individual boards on libfdt

Now that boards are enabled by default and the "CONFIG_FOO=y"
entries are gone from configs/devices/, there cannot be any more
a conflicts between the default contents of configs/devices/
and a failed "depends on" clause.

With this change, each individual board or target can express
whether it needs FDT. It can then include the common code in the
build via "select DEVICE_TREE", which will also as tell meson to link
with libfdt.

This allows building non-microvm x86 emulators without having
libfdt available.

Add a target-specific Kconfig. We need the definitions in Kconfig so

Two architecture have a particularity, ARM and MIPS. As their
translators have been split you can potentially build a plain 32 bit
build along with a 64-bit version including the 32-bit subset.
