Litex SoC controller supports reboot function by toggling the first
bit of the ctrl register. Add a reset driver so other software can
use it.

Refactor ATCSMU (System Management Unit) support by moving it from a
system utility into a dedicated FDT-based HSM driver.
Key changes include:
- Moving the functions in lib/utils/sys/atcsmu.c into the new HSM driver
- Moving hart start and stop operations on AE350 platform into the new
HSM driver
- Converting the assembly-based functions in sleep.S to C code for the
readability
- Updating the ATCWDT200 driver

In the past, we used fdt_reset_thead to help customers with prototype
verification. However, with the emergence of the Big-little SoC system,
it can no longer meet the demand. Therefore, we use zero_stage_boot
instead of fdt_reset_thead. It cleans up the opensbi code and ends the
disputation of reset_sample's dts.
This patch removes the fdt_reset_thead component and updates the related
doc.

Let us have common FDT based reset driver for syscon reboot and
poweroff. The device tree bindings for syscon reboot and poweroff
are already available in the Linux kernel sources.

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>;
};

We update FDT support makefile to use kconfig for enabling/disabling.
To avoid compilation errors, we also enable FDT for each platform.
