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.

Using "void *" in arithmetic causes errors with strict compiler settings:
"error: pointer of type 'void *' used in arithmetic [-Werror=pointer-arith]"
Avoid these by calculating on "char *" where 1-byte data size is assumed.

To support different handlers for different types of resets, we are
adding a sbi_list of restart handlers.
Instead of sbi_system_reset_set_device we use
sbi_system_reset_add_device to reflect the actual meaning.

One of the watchdogs in the D1 SoC provides a "soft reset" function,
which allows software to immediately reset the entire SoC. Add a driver
so it can implement the SBI system reset function.
