    scripts: sercomm-pid.py: use uppercase hwid in pid
    
    Sercomm uses uppercase for hexadecimal representation of the device
    hardware IDs in factory image PID. This commit brings the sercomm-pid.py
    script into compliance with the original Sercomm algorithm.
    
    Example
    -------
    +--------+-------------+-----------+-------------+
    | Device | PID (before | PID       | PID (after  |
    | HWID   | the commit) | (Sercomm) | the commit) |
    +--------+-------------+-----------+-------------+
    | CPJ    | 43 50 4a    | 43 50 4A  | 43 50 4A    |
    +--------+-------------+-----------+-------------+
