Contribution description

The commit fixes the order of entries in the MTD pointer XFA mtd_dev_xfa according to their index by using the index as the priority in the XFA.

Since PR #19465, the pointers to existing MTD devices mtd0, mtd1, ... mtd<n> are hold in the MTD pointer XFA mtd_dev_xfa. The order of these pointers in the XFA should correspond to their index so that mtd_dev_xfa[i] gives mtd<i> which points to the i-th MTD. For that purpose the idx parameter of the MTD_XFA_ADD macro has to be used as priority.

Testing procedure

000103a0 T mtd0
000103a4 T mtd2

With this PR, the command should give:

000103c4 T mtd0
000103c8 T mtd1
000103cc T mtd2
