coresight: csr: Add multiple CSR devices support
Add a CSR device list in CSR driver to support multiple CSR devices. CSR
device structure is initialized in probe and added to the list. Add CSR
device structure as parameter of CSR function. Change the caller of CSR
functions to align with this change.
