The ppm_lock really only needs to be hold during 2 functions: ucsi_reset_ppm() and ucsi_run_command(). Push the taking of the lock down into these 2 functions, renaming ucsi_run_command() to ucsi_send_command() which was an existing wrapper already taking the lock for its callers. This simplifies things for the callers and removes the difference between ucsi_send_command() and ucsi_run_command() which has led to various locking bugs in the past.
