## Summary
Remove the iLLD dependency from the TriCore hardware debug monitor
(`tricore_hwdebug.c`), continuing the de-iLLD effort for `arch/tricore`.
The debug CSFR numbers, trigger-event register (TR0..TR7) addresses,
TREVT bit-field offsets and the CBS_OEC register address are now defined
locally with a `TC_` prefix, so the file no longer depends on the iLLD
SFR headers (`IfxCpu_bf.h`, `IfxCbs_reg.h`) nor the iLLD intrinsics
(`__mfcr`/`__mtcr`). Register accesses use the `tricore_mfcr`/
`tricore_mtcr` macros, and the `DBGTCR`/`DBGCFG`/`DBGACT` bit-field
unions are replaced with explicit shifts.
The `TC_` prefix avoids a redefinition clash with the iLLD `CPU_*`
namespace, which is still pulled in transitively through `arch/irq.h`.
## Impact
Behavior is unchanged; this is a pure de-iLLD refactor.
## Testing
- Build: `triboard_tc4x9_com:nsh` (TC1V8) and `a2g-tc397-5v-tft:nsh`
(TC1V6) both compile with 0 errors and no redefinition warnings.
- `checkpatch.sh`: pass.
- EVB (TC4X7): boots to NuttShell; the `debugpoint` test app confirms
breakpoints trigger identically before and after the change. Verified
on real hardware that the watchpoint trigger itself fires at the
correct faulting PC (any watchpoint-callback discrepancy in the test
app is pre-existing and unrelated to this change).
