ARM: multi_v7_defconfig: Enable additional support for RZ/N1 platforms

Increase build and test coverage by enabling support for the A5PSW
Ethernet switch, pin, watchdog, USB Function, RTC, and DMA mux
controllers on the Renesas RZ/N1 SoC and the RZN1D-DB development board.

All drivers for the above are modular, except for the pin control
driver.
