37696fa746 soc: kunpeng_hccs: fix size_t format string
Printing a size_t using the %lu format string causes a warning on
architectures that define the type as 'unsigned int':

In file included from include/linux/device.h:15,
                 from include/linux/acpi.h:14,
                 from drivers/soc/hisilicon/kunpeng_hccs.c:25:
drivers/soc/hisilicon/kunpeng_hccs.c: In function 'hccs_get_bd_info':
drivers/soc/hisilicon/kunpeng_hccs.c:441:25: error: format '%lu' expects argument of type 'long unsigned int', but argument 3 has type 'size_t' {aka 'unsigned int'} [-Werror=format=]

Use the correct %zu format instead.

800b432012 Arm SCMI updates for v6.6
The main addition this time is the support for SCMI v3.2 perf level
 indexing mode. SCMI v3.2 adds support for hardware which works on
 performance indices, instead of levels. Certain platforms use indices
 to identify performance levels. Level Indexing Mode is used to describe
 such platform behavior. All commands which utilize performance level
 as a parameter need to specify the corresponding level index instead of
 the performance level when Level Indexing Mode is used.
 
 While at it, these changes also include hardening of all the internal
 accesses to the performance domain information.

Arm SCMI updates for v6.6

The main addition this time is the support for SCMI v3.2 perf level
indexing mode. SCMI v3.2 adds support for hardware which works on
performance indices, instead of levels. Certain platforms use indices
to identify performance levels. Level Indexing Mode is used to describe
such platform behavior. All commands which utilize performance level
as a parameter need to specify the corresponding level index instead of
the performance level when Level Indexing Mode is used.

While at it, these changes also include hardening of all the internal
accesses to the performance domain information.

31c7c1397a firmware: arm_scmi: Add v3.2 perf level indexing mode support
SCMI v3.2 adds PERF protocol support to optionally define performance
domains that cannot be represented on a linear scale; the platform firmware
can declare the performance levels of a domain as being 'level indexed' and
provide an indicative frequency associated to each of those levels, with
such indexes not required anymore to be contiguous nor to satisfy any
linear-scaling constraint: when level-indexing is available for a domain,
the platform will expect to deal with SCMI requests using indexes instead
of performance levels for that domain.

Add level-indexing mode support to the PERF protocol implementation while
maintaining unchanged the protocol operations interface exposed by PERF;
all the required mapping from performamce levels/frequencies to the
corresponding level indexes is carried out transparently by the core PERF
protocol support: as a consequence no change is either required in any
SCMI driver using the PERF protocol, even when using level indexing.

Currently the entries have regexs but in absolute paths. The "N:" entries
can deal with all files and directories irrespective of the depth/path
matching the regex patterns.

Simplifies the entry by making using "N:" and dropping "F:" with absolute
