Remove function names from logging calls in src/schedule, src/math, src/init, and src/idc

[Copilot]

This patch removes function names from the beginning of logging messages in the target directories as part of code cleanup efforts. Function names in log messages are redundant since modern logging systems and debuggers can provide this information automatically.

Changes Made

Pattern 1: Complete function name removal

// Before
tr_dbg(&ll_tr, "zephyr_domain_register()");

// After  
tr_dbg(&ll_tr, "");

Pattern 2: Function name prefix removal while preserving message

// Before
tr_err(&twb_tr, "scheduler_twb_task_init(): memory alloc failed");

// After
tr_err(&twb_tr, "memory alloc failed");

Scope

• Directories modified: src/schedule/, src/math/, src/init/, src/idc/
• Files modified: 11 total (.c files only)
• Logging macros updated: tr_info(), tr_dbg(), tr_err(), tr_warn(), LOG_INF(), LOG_DBG(), LOG_ERR(), LOG_WRN(), and component-specific variants
• Changes: 59 insertions, 60 deletions (minimal surgical changes)

Validation

• All modified files pass checkpatch.pl validation with no new errors
• Log levels and logic remain completely unchanged
• Only log message content was modified, preserving meaningful error descriptions
• No functional code changes were made

Files Modified

• src/schedule/dma_multi_chan_domain.c
• src/schedule/dma_single_chan_domain.c
• src/schedule/ll_schedule.c
• src/schedule/schedule.c
• src/schedule/zephyr_dma_domain.c
• src/schedule/zephyr_domain.c
• src/schedule/zephyr_dp_schedule.c
• src/schedule/zephyr_ll.c
• src/schedule/zephyr_twb_schedule.c
• src/math/power.c
• src/idc/idc.c

This cleanup improves code consistency and removes redundant information from log messages while maintaining all essential debugging information.
