Account for more than only 23 GPIOs in LPASS Low Power Island pinctrl
generic driver. The previous value 23 was chosen to satisfy existing
SoC-specific drivers. However SM4250 LPI pinctrl uses more than 23 GPIOs
and its probe routine fails on:
if (WARN_ON(data->npins > MAX_NR_GPIO))
return -EINVAL;
with the following message:
