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.

The GPIO reset driver supports reset and poweroff. But not all boards
support both. gpio_system_reset_check() must detect this situation.

We should use sbi_timer_mdelay() instead of custom gpio_mdelay() in
the gpio reset driver.

The generic GPIO reset driver has two entries in the match table:
"gpio-poweroff", "gpio-reset". Only the first entry is considered by
fdt_reset_init().
Define "gpio-poweroff" and "gpio-reset" as compatibility strings of two
separate reset drivers. They still can share code.
