Instead of returning the unused entry address from riscv_load_firmware()
instead return the end address. Also return the end address from
riscv_find_and_load_firmware().
This tells the caller if a firmware was loaded and how big it is. This
can be used to determine the load address of the next image (usually the
kernel).

Currently we log interrupts and exceptions using the trace backend in
riscv_cpu_do_interrupt(). We also log exceptions using the interrupt log
mask (-d int) in riscv_raise_exception().
This patch converts riscv_cpu_do_interrupt() to log both interrupts and
exceptions with the interrupt log mask, so that both are printed when a
user runs QEMU with -d int.

Add QemuSpiceOps struct. This struct holds function pointers to the
spice functions. It will be initialized with pointers to the stub
functions. When spice gets initialized the function pointers will
be re-written to the real functions.
The spice stubs will move from qemu-spice.h to spice-module.c for that,
because they will be needed for both "CONFIG_SPICE=n" and "CONFIG_SPICE=y
but spice module not loaded" cases.

If an address is out of range, do not attempt to erase it:
