lib: utils: support both of gpio-poweroff, gpio-reset 

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.

Fixes: e3d6919d10 ("lib: utils/reset: Add generic GPIO reset driver")
