commit 339b9329ff7be01d03c3a55301e1ef1a2ea57953

    l1sap: fix rach reason (ra) parsing
    
    The ra parameter indicates the reason for the received rach
    request. osmo-bts uses the ra parameter to determine if the
    received rach request is packet access related. If yes,
    osmo-bts will forward the request to the PCU.
    
    In order to determine if the ra is packet related or not,
    the higher 4 bits must be equel to 0x7 and at least one of
    the lower 4 bits must be zero.
    
    The current method lacks checking of the lower 4 bits. It
    would also accept 0b01111111, which is reserved for future
    use. This commit extends the check to take also the last
    4 bits into accound.
