clang-format: re-format for clang-18

clang-format-18 isn't compatible with the clang-format-17 output, so we

handles lambda formatting also changed, so we have made changes to the
organization default style format to better handle lambda formatting.

See I5e08687e696dd240402a2780158664b7113def0e for updated style.

If the device driver is ibm-cpffps, read the MFR_POUT_MAX value
(max_power_out). Only enable INPUT_HISTORY data collection if it is not
the 1400W IBM power supply (MSB/LSB results in 30725 for 1400). The
1400W IBM power supply appears to cause problems on the bus when
an INPUT_HISTORY PMBus command read occurs.

Tested:

psu-ng: Power supply class updates for input history

Update the meson files to include the record_manager with the
phosphor-psu-monitor application.

Since we do not want to blindly enable input history for all power
supplies, base the enablement of the feature off of the driver name.
Change the PowerSupply class to require the driver name be passed in,
and pass that down via the PSUManager during the configuration
determination.

Add a server manager to the PSUManager to handle the INPUT HISTORY data
that will be under /org/open_power/sensors.

The INPUT_HISTORY command is handled via a sysfs file in binary format,
so add in a readBinary() base function to allow for mock testing.

If communication restores, we may be able to detect what caused the read
failure, or otherwise detect or clear new faults.

While attempting to look into creating and detecting power supply fan

Read the input voltage reported by pmbus for each PSU. Determine the

Tested:
Verified in Rainier 2U that the 2 present PSUs had a pmbus
voltage value of 208000 mV, which is then translated to a 220V PSU, and
that value is validated against the supported configuration.
Verified the additional data strings by printing them with debug

psu-ng: Updates to allow PSU missing on startup

If the power supply is missing when the application starts up, the
created PMBus interface will log an INFO message about being unable to

but in the inventoryChange() interface, when the power supply goes
present, be sure to call the findHwmonDir() function to update the
directory/file changes that may occur when the device driver binds.

Use simulator to verify no changes when both present and chassison.
Use simulator to mark 2nd PSU missing, restart application, mark 2nd
PSU as present and verify no PSU communication problems.
Use simulator to mark 1st PSU missing, restart application, mark 1st
