Make it possible to specify a custom target device offset. This is
required for the upcoming i.MX8MN/P QSPI update handler which reuse the
common update handler logic. For i.MX8MN/P QSPI boot the image must be
written to a 4K target-device-offset but before that we need to strip
the SD flash-header-offset:
Generic-Image Target
+-------+ 0x0 +-------+ 0x0
| .... | | .... |
+-------+ flash-header-offset +-------+ target-device-offset
| FCFB | | FCFB |
+-------+ +-------+
| .... | | .... |
+-------+ +-------+
| IVT | | IVT |
+-------+ +-------+
| .... | | .... |
+-------+ +-------+
