qga: add command guest-get-devices for reporting VirtIO devices
Add command for reporting devices on Windows guest. The intent is not so
much to report the devices but more importantly the driver (and its
version) that is assigned to the device. This gives caller the
information whether VirtIO drivers are installed and/or whether
inadequate driver is used on a device (e.g. QXL device with base VGA
driver).

hw/riscv: hart: Add a new 'resetvec' property
RISC-V machines do not instantiate RISC-V CPUs directly, instead
they do that via the hart array. Add a new property for the reset
vector address to allow the value to be passed to the CPU, before
CPU is realized.

target/riscv: cpu: Add a new 'resetvec' property
Currently the reset vector address is hard-coded in a RISC-V CPU's
instance_init() routine. In a real world we can have 2 exact same
CPUs except for the reset vector address, which is pretty common in
the RISC-V core IP licensing business.
Normally reset vector address is a configurable parameter. Let's
create a 64-bit property to store the reset vector address which
covers both 32-bit and 64-bit CPUs.

The kernel does a 16-bit write when powering off the machine, which
was allowed before commit 5d971f9e67 ("memory: Revert "memory: accept
mismatching sizes in memory_region_access_valid""). Make min_access_size
match reality so that the machine can shut down properly now.

target/riscv: Fix bug in getting trap cause name for trace_riscv_trap
When the cause number is equal to or greater than 23, print "(unknown)" in
trace_riscv_trap. The max valid number of riscv_excp_names is 23, so the last
excpetion "guest_store_page_fault" can not be printed.
In addition, the current check of cause is invalid for riscv_intr_names. So
introduce riscv_cpu_get_trap_name to get the trap cause name.
