Leave ARM_CP_SVE, removing ARM_CP_FPU; the sve_access_check

We don't actually implement SD command CRC checking, because
for almost all of our SD controllers the CRC generation is
done in hardware, and so modelling CRC generation and checking
would be a bit pointless. (The exception is that milkymist-memcard
makes the guest software compute the CRC.)
As a result almost all of our SD controller models don't bother
to set the SDRequest crc field, and the SD card model doesn't
check it. So the tracing of it in sdbus_do_command() provokes
Coverity warnings about use of uninitialized data.
Drop the CRC field from the trace; we can always add it back
if and when we do anything useful with the CRC.
Fixes Coverity issues 1386072, 1386074, 1386076, 1390571.

KVM implies V7VE, which implies ARM_DIV and THUMB_DIV. The conditional
detection here is therefore unnecessary. Because V7VE is already
unconditionally specified for all KVM hosts, ARM_DIV and THUMB_DIV are
already indirectly specified and do not need to be included here at all.

For aa64 advsimd, we had been passing the pre-indexed vector.
However, sve applies the index to each 128-bit segment, so we
need to pass in the index separately.
For aa32 advsimd, the fp32 operation always has index 0, but
we failed to interpret the fp16 index correctly.

When running dtc on the guest /proc/device-tree we get the
following warning: Warning (unit_address_vs_reg): Node /memory
has a reg or ranges property, but no unit name".
Let's fix that by adding the unit address to the node name. We also
don't create the /memory node anymore in create_fdt(). We directly
create it in load_dtb. /chosen still needs to be created in create_fdt
as the uart needs it. In case the user provided his own dtb, we nop
all memory nodes found in root and create new one(s).
