[ Upstream commit 86b9ea6412af41914ef6549f85a849c3b987f4f3 ]
Before commit 74be4babe72f ("net: dsa: do not enable or disable non user ports"), gswip_port_enable/disable() were also executed for the cpu port in gswip_setup() which disabled the cpu port during initialization.
Let's restore this by removing the dsa_is_user_port checks. Also, let's clean up the gswip_port_enable() function so that we only have to check for the cpu port once. The operation reordering done here is safe.
