[PATCH v1 6/8] arm: socfpga: n5x: Switch firewall setup to device model

[Chen Huei Lok]

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

Also, remove `CONFIG_SPL_DRIVERS_MISC_SUPPORT` from the defconfig,
as it's no longer required.
