gpio: pisosr: Read "ngpios" as u32

Browse Source 
The generic "ngpios" property is encoded as a normal uint32 cell. The
pisosr driver stores it in the gpio_chip field, but reading it with a
u16 helper does not match the DT property encoding.

Read "ngpios" as u32 and keep the existing assignment to the chip
field.
