coresight-cti: Fix cpu-cti probe fail
A function whose return value is negative indicates
an error, not a non-zero value. A return value of
1 or 0 means the function executed successfully.
In many cases, the return value is negative, such
as dev->power.disable_depth > 0, dev->power.runtime_error
is set
Add verification to the coresight_cti_ctx_save and
coresight_cti_ctx_restore to ensure that the device
is in active status while reading and writing.
