[PATCH v6 2/2] coresight: cti: Add Qualcomm extended CTI support

Hi Leo & Mike
Based on Leo’s suggestions, I created a new patch, but there are three points that do not fully align with his recommendations:
1. The helper function for returning the register address now returns only the offset, because returning the full address would conflict with cti_write_single_reg.
2. For registers such as triginstatus1...3, I defined additional macros CTITRIGINSTATUS1...3. This is because CTITRIGINSTATUS + 0x4 equals CTITRIGOUTSTATUS, and to avoid conflicts with existing macros, I chose numbers starting from 0x1000 for the new definitions.
3. Regarding the visibility of attributes for triginstatus1...3, since coresight_cti_reg produces an anonymous variable that cannot be directly referenced, I used coresight_cti_regs_attrs[i] to obtain the attribute corresponding to triginstatus1.
I appreciate both suggestions. After reviewing them, I lean toward Mike's approach.
