The map pointer is freed by pinctrl_utils_free_map(). It must not be a
devm_ pointer or it leads to a double free when the device is unloaded.
This is similar to a couple bugs Harshit Mogalapalli fixed earlier in
commits 3fd976afe974 ("pinctrl: nuvoton: fix a double free in
ma35_pinctrl_dt_node_to_map_func()") and 4575962aeed6 ("pinctrl: sophgo:
fix double free in cv1800_pctrl_dt_node_to_map()").
Fixes: a83c29e1d145 ("pinctrl: spacemit: add support for SpacemiT K1 SoC")
