[PATCH v2 6/8] arm: socfpga: n5x: switch firewall setup to driver model

[Chen Huei Lok]

Move the system manager and L3 interconnect firewall configuration
from a dedicated firewall_setup() function to using the driver model
(uclass_get_device_by_name()). This removes the hardcoded firewall
setup in SPL and relies on the driver model, making the code more
maintainable and aligned with upstream practices.
