    ppc64-diag: Move trim_trail_space() function to common/utils.c
    
    Currently, trim_trail_space() function is used in diags/diag_nvme.c file
    to be able to trim trailing white spaces from a given location code. Allow
    code reusability by moving the trim_trail_space() function from
    diags/diag_nvme.c to common/utils.c.
