!596 drivers/coresight: Add UltraSoc System Memory Buffer driver

Merge Pull Request from: @huangfangrun 
 
Add driver for UltraSoc SMB(System Memory Buffer) device. SMB provides a way to buffer messages from ETM, and store these "CPU instructions trace" in system memory. The SMB device is identifier as ACPI HID "HISI03A1". Device system memory address resources are allocated using the _CRS method and buffer modes is the circular buffer mode.

SMB is developed by UltraSoc technology, which is acquired by Siemens, and we still use "UltraSoc" to name driver.
