Macro definition is added for acpi sleep control register, ged emulation
driver can use the macro , also it can be used in FDT table if ged is
exposed with FDT table.

hw/loongarch/virt: Add FDT table support with acpi ged pm register
ACPI ged is used for power management on LoongArch virt platform, in
general it is parsed from acpi table. However if system boot directly from
elf kernel, no UEFI bios is provided and acpi table cannot be used also.
Here acpi ged pm register is exposed with FDT table, it is compatbile
with syscon method in FDT table, only that acpi ged pm register is accessed
with 8-bit mode, rather with 32-bit mode.

hw/loongarch/boot: Refactor EFI booting protocol generation
Refector EFI style booting data structure generation to
support 32bit EFI variant on LoongArch32 CPU.
All data structs are filled with padding members if necessary
and marked as QEMU_PACKED to avoid host ABI alignment impact.
Host endian is being cared as well.
It also fixed various problems in old implementation such
as null pointer on empty string, memory desc map_size not set,
incorrect memory map definition and so on.

Variable env->cf[i] is defined as bool type, it is treated as int type
with shift operation. However the max possible width is 56 for the shift
operation, exceeding the width of int type. And there is existing api
read_fcc() which is converted to u64 type with bitwise shift, it can be
used to dump fp registers into coredump note segment.

copy-before-write: allow specifying minimum cluster size
In the context of backup fleecing, discarding the source will not work
when the fleecing image has a larger granularity than the one used for
block-copy operations (can happen if the backup target has smaller
cluster size), because cbw_co_pdiscard_snapshot() will align down the
discard requests and thus effectively ignore then.
To make @discard-source work in such a scenario, allow specifying the
minimum cluster size used for block-copy operations and thus in
particular also the granularity for discard requests to the source.
The type 'size' (corresponding to uint64_t in C) is used in QAPI to
rule out negative inputs and for consistency with already existing
@cluster-size parameters. Since block_copy_calculate_cluster_size()
uses int64_t for its result, a check that the input is not too large
is added in block_copy_state_new() before calling it. The calculation
in block_copy_calculate_cluster_size() is done in the target int64_t
type.

Log Message:

block/reqlist: allow adding overlapping requests
Allow overlapping request by removing the assert that made it
impossible. There are only two callers:
1. block_copy_task_create()
It already asserts the very same condition before calling
reqlist_init_req().
2. cbw_snapshot_read_lock()
There is no need to have read requests be non-overlapping in
copy-before-write when used for snapshot-access. In fact, there was no
protection against two callers of cbw_snapshot_read_lock() calling
reqlist_init_req() with overlapping ranges and this could lead to an
assertion failure [1].
In particular, with the reproducer script below [0], two
cbw_co_snapshot_block_status() callers could race, with the second
calling reqlist_init_req() before the first one finishes and removes
its conflicting request.
