mt7621: Make ER-X-SFP factory image compatible with EP-R6
The version inside the compat file determines, if a firmware supports
a specific device. I have not yet fully understood, how this is checked,
but it only seems to indicate which devices are supported by a specific
version of the combined vendor firmware. Devices assume that subsequent
versions, starting with the version that initially added support for a
specific device, are always compatible.
The first compat version that added support for the EP-R6 was '21001:7',
but OpenWrt did use '21001:6' before. This is why the factory image could
not be flashed using the vendor software, but only using TFTP.
The compat version has been bumped by the vendor a few times, but more
devices have been added since (e.g. ER-10X). Because OpenWrt currently
only supports the ER-X, ER-X-SFP and EP-R6, the compat version is
incremented to the version that first supported the EP-R6, which is
'21001:7'.
This allows the factory image to be flashed on EP-R6 without TFTP.
