drivers/coresight: Add UltraSoc System Memory Buffer driver
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.
