lib: utils/reset: Use fdt_driver for initialization
...
The reset driver subsystem does not need any extra data, so it can use
`struct fdt_driver` directly. The generic fdt_reset_init() performs a
best-effort initialization of all matching DT nodes. Platform-specific
logic expects exactly one DT node to match a single driver. This is
accomplished by using fdt_driver_init_one() with a local list containing
that one driver.

lib: utils/reset: Add Andes fdt reset driver support
...
Add ATCWDT200 as reset device of AE350 platform, this driver requires
SMU to program the reset vector registers before triggering WDT software
restart signal.
dts example:
smu@f0100000 {
compatible = "andestech,atcsmu";
reg = <0x00000000 0xf0100000 0x00000000 0x00001000>;
};
wdt: wdt@f0500000 {
compatible = "andestech,atcwdt200";
reg = <0x00000000 0xf0500000 0x00000000 0x00001000>;
interrupts = <3 4>;
interrupt-parent = <&plic0>;
clock-frequency = <15000000>;
