mb/google/poppy/variants/nami: Perform PL2 setting in variant_devtree_udpate
This change moves PL2 override to variant_devtree_update for two reasons: 1. This function was added to basically override devtree settings in variant specific code. So, it would be a good idea to perform all the overrides in a single place. 2. Adding a device for performing nami_enable would require changes to devicetree and special handling for calling this device enable. Thus, nami_enable was never getting called.
