[Bug] Planck Rev. 6 'set_single_persistent_default_layer' Not Functioning as Intended

[hobby-grade]

Describe the Bug

When changing a layer, the layer does not persist between power cycles. This used to persist when using the 'set_single_persistent_default_layer' function. Before, if I changed to layer 1 and unplugged my keyboard and plugged it back in, it would be on layer 1 again. Now it returns to layer 0 when reconnected.

This issue has been resolved by @zvecr who discovered that the BOOTMAGIC_ENABLE flag was set to "full" in the rev6 'rules.mk' Correct flag should be BOOTMAGIC_ENABLE = yes. This seems to solve the issue.
