[PATCH] firmware: arm_scmi: Add new sensor unit types

[Artem Shimko <a.shimko.dev@gmail.com>]

Add support for two new sensor unit types introduced in Arm SCMI
- STATE_BINARY (0x5E): Binary state (1: enabled/on, 0: disabled/off)
- BYTES_SEC (0x5F): Bytes per second

These unit types are used for sensors that report binary state information
and data transfer rate measurements respectively.

Hello,

This patch adds definitions for two new sensor unit types that were
introduced in the Arm System Control and Management Interface (SCMI)
Specification version 4.0:

STATE_BINARY (0x5E) - Used for sensors that represent binary states
where:
1 indicates enabled/on state
0 indicates disabled/off state

BYTES_SEC (0x5F) - Used for sensors that measure data transfer rates
in bytes per second

These additions ensure compatibility with SCMIv4.0 and allow proper
handling of binary state sensors and bandwidth measurement sensors
in the Linux SCMI driver.

The patch follows the existing pattern for sensor unit type definitions
and maintains backward compatibility with previous SCMI versions.

Thank you for your consideration.

Best regards,
Artem Shimko
