[PATCH v2 1/2] pinctrl: single: Fix error return code in pcs_parse_bits_in_pinctrl_entry()

[Zhen Lei]

Fix to return -ENOTSUPP instead of 0 when PCS_HAS_PINCONF is true, which
is the same as that returned in pcs_parse_pinconf().

Fixes: 4e7e8017a80e ("pinctrl: pinctrl-single: enhance to configure multiple pins of different modules")
