[PATCH v2 2/8] arm: dts: socfpga: n5x: enable DT register settings and update GMAC nodes

[Chen Huei Lok]

Enable register settings in the N5X U-Boot device tree by adding
firewall configuration nodes under the L3 interconnect firewall.
These settings disable OCRAM security at the CCU and relax MPFE
firewall restrictions required during early boot.

Update the GMAC nodes to include proper compatible,
reset-names, and clock-names properties, explicitly setting
their status.

Remove the clocks property from the QSPI node in
socfpga_n5x_socdk-u-boot.dtsi. The QSPI controller clock is obtained
via cm_get_qspi_controller_clk_hz(), so the device tree clock
reference is unnecessary.

Additionally, include socfpga_soc64_u-boot.dtsi and rename the
soc node to soc at 0 in socfpga_n5x-u-boot.dtsi to align with
the common SoCFPGA DT layout.
