[PATCH] mmc: sdhci-s3c: Use NULL instead of 0 for pointers

[Tushar Behera]

The third argument for of_get_property() is a pointer, hence pass
NULL instead of 0.

Fixes following sparse warning.
drivers/mmc/host/sdhci-s3c.c:452:48: warning: Using plain integer as
NULL pointer
drivers/mmc/host/sdhci-s3c.c:457:52: warning: Using plain integer as
NULL pointer
