disp: msm: display error log signature alignment

Ensure SDE_ERROR error log print function name and line number.
Add a macro DISP_DEV_ERR as a wrapper of dev_err to ensure origin dev_err
will print function name and line number.
This would help with analysis of errors reported with automated testing.

Expected display error log format:
  [FUNCTION_NAME:line] ERROR_MESSAGE
