spi: npcm: fix u32 csgpio being checked for less than zero
The u32 variable csgpio is being checked for an error return
from the call to of_get_named_gpio, however, since this is unsigned
this comparison will always be false. Fix this by making csgpio an
int and fix up the %u format specifiers to %d accordingly.
Detected by CoverityScan, CID#1475476 ("Unsigned compared against 0")
Fixes: 2a22f1b30cee ("spi: npcm: add NPCM PSPI controller driver")
