Without the proper aligned image size we may encounter host load errors
like:
| found i.MX8MP USB device [1fc9:0146]
| No dcd table in this ivt
| dl_command err=-1, last_trans=-1
| 4 in err=-4, last_trans=0 00 00 00 00
The reason for this is that we asked only for the required bytes while
the host tries to send the complete image which may contain alignment
bytes at the end.
Fix this by request always 4K aligned sizes.
