commit 4e7e8017 (pinctrl: pinctrl-single: enhance to configure multiple pins of different modules) improved support for pinctrl-single,bits option, but also caused a regression in parsing badly configured mask data. If the masks in DT data are not quite right, pcs_parse_bits_in_pinctrl_entry() can end up in an infinite loop, trashing memory at the same time. Add a check to verify that each loop actually removes bits from the 'mask', so that the loop can eventually end. Signed-off-by:
