In npcm_pspi_probe(), current code set platform_set_drvdata(pdev, master);
so in npcm_pspi_remove() platform_get_drvdata(pdev) will return pointer to
master rather than priv. Fix it.

The compiler has no way to know that rsize 1 or 2 are the only valid
values. Also simplify the code a bit with early return.
The warning was:
drivers/spi/spi-npcm-pspi.c:215:6: warning: 'val' may be used uninitialized in this function [-Wmaybe-uninitialized]

There is an IS_ERR() vs PTR_ERR() typo here. The current code returns 1
but we want to return the negative error code.

drivers/spi/spi-npcm-pspi.c:470:3-8: No need to set .owner here. The core will do it.
Remove .owner field if calls are used which set it automatically

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.
