Rename TYPE_ARMSSE to TYPE_ARM_SSE, and ARMSSE*() type checking
macros to ARM_SSE*().
This will avoid a future conflict between an ARM_SSE() type
checking macro and the ARMSSE typedef name.

Instead of passing an unsafe pointer to artist_rop8(), pass the vram_buffer and
the offset. We can now check if the offset is in range before accessing it.

We extend RISC-V virt machine to allow creating a multi-socket
machine. Each RISC-V virt machine socket is a NUMA node having
a set of HARTs, a memory instance, a CLINT instance, and a PLIC
instance. Other devices are shared between all sockets. We also
update the generated device tree accordingly.
By default, NUMA multi-socket support is disabled for RISC-V virt
machine. To enable it, users can use "-numa" command-line options
of QEMU.
Example1: For two NUMA nodes with 2 CPUs each, append following
to command-line options: "-smp 4 -numa node -numa node"
Example2: For two NUMA nodes with 1 and 3 CPUs, append following

HAD is a mandatory features with SMMUv3.1 if S1P is set, which is

if the HAD0/1 bit is set, the APTable field of table descriptors
walked through TTB0/1 is ignored.

Enhance the smmu_iotlb_inv_iova() helper with range invalidation.
This uses the new fields passed in the NH_VA and NH_VAA commands:
the size of the range, the level and the granule.
As NH_VA and NH_VAA both use those fields, their decoding and
handling is factorized in a new smmuv3_s1_range_inval() helper.

Let's introduce an helper for S1 IOVA range invalidation.
This will be used for NH_VA and NH_VAA commands. It decodes
the same fields, trace, calls the UNMAP notifiers and
invalidate the corresponding IOTLB entries.
At the moment, we do not support 3.2 range invalidation yet.
So it reduces to a single IOVA invalidation.
Note the leaf bit now is also decoded for the CMD_TLBI_NH_VAA
command. At the moment it is only used for tracing.

At the moment each entry in the IOTLB corresponds to a page sized
mapping (4K, 16K or 64K), even if the page belongs to a mapped
block. In case of block mapping this unefficiently consumes IOTLB
entries.
Change the value of the entry so that it reflects the actual
mapping it belongs to (block or page start address and size).
Also the level/tg of the entry is encoded in the key. In subsequent
patches we will enable range invalidation. This latter is able
to provide the level/tg of the entry.
Encoding the level/tg directly in the key will allow to invalidate
using g_hash_table_remove() when num_pages equals to 1.

Introduce a specialized SMMUTLBEntry to store the result of
the PTW and cache in the IOTLB. This structure extends the
generic IOMMUTLBEntry struct with the level of the entry and
the granule size.
Those latter will be useful when implementing range invalidation.

Here's my first pull request for qemu-5.2, which has quite a few
accumulated things. Highlights are:
* Preliminary support for POWER10 (Power ISA 3.1) instruction emulation
* Add documentation on the (very confusing) pseries NUMA configuration
* Fix some bugs handling edge cases with XICS, XIVE and kernel_irqchip
* Fix icount for a number of POWER registers
* Many cleanups to error handling in XIVE code
* Validate size of -prom-env data
