[PATCH 1/4] firmware: arm_scmi: Read sensor config as 32-bit value

[Sudeep Holla]

The SENSOR_CONFIG_GET response contains a 32-bit sensor_config field,
and the xfer is initialized with a 4-byte RX buffer. Reading it with
get_unaligned_le64() can consume bytes past the returned payload.

Use get_unaligned_le32() to match the protocol layout and the allocated
response size.
