scsi: ufs: core: bsg: Add advanced RPMB support in ufs_bsg

Add advanced RPMB support in ufs_bsg:

 1. According to the UFS specification, only one RPMB operation can be
    performed at any time. We can ensure this by using reserved slot and
    its dev_cmd sync operation protection mechanism.

 2. For Advanced RPMB, RPMB metadata is packaged in an EHS (Extra Header
    Segment) of a command UPIU, and the corresponding reply EHS (from the
    device) should also be returned to the user space.  bsg_job->request
    and bsg_job->reply allow us to pass and return EHS from/back to
    userspace.

Compared to normal/legacy RPMB, the advantages of advanced RPMB are:

 1. The data length in the Advanced RPMB data read/write command can be
    larger than 4KB. For the legacy RPMB, the data length in a single RPMB
    data transfer is 256 bytes.

 2. All of the advanced RPMB operations will be a single command. For
    legacy RPMB, take the read write-counter value as an example, you need
    two commands (first SECURITY PROTOCOL OUT, then second SECURITY
    PROTOCOL IN).
