If used 64 bit compiler GCC warns that:
drivers/i2c/busses/i2c-s3c2410.c: In function ‘s3c24xx_get_device_quirks’:
drivers/i2c/busses/i2c-s3c2410.c:168:10: warning: cast from pointer to integer
of different size [-Wpointer-to-int-cast]
This patch fixes this by converting "unsigned int" to "kernel_ulong_t".

Changes since v1:
- using "kernel_ulong_t" instead of "unsigned long" for consistency.
- take care of formatting issues as pointed by Wolfram Sang.
