pinctrl: sophgo: fix double free in cv1800_pctrl_dt_node_to_map()

Browse Source 
'map' is allocated using devm_* which takes care of freeing the allocated
data, but in error paths there is a call to pinctrl_utils_free_map()
which also does kfree(map) which leads to a double free.

Use kcalloc() instead of devm_kcalloc() as freeing is manually handled.
