When a ppa_list with vblks is expanded, it can either go block or
plane first. Currently it is been plane first. This works well for a
single vblk that is expanded, but fails for controllers that
require data for all planes is grouped together. Make the ppa_list
expand first expand with block, and then plane to support this
behavior.
Before (2 blocks, 4 planes per vblk)
idx block plane
0 0 0
1 1 0
2 0 1
3 1 1
4 0 2
5 1 2
6 0 3
7 1 3
After
idx block plane
0 0 0
1 0 1
2 0 2
3 0 3
4 1 0
5 1 1
6 1 2
7 1 3
