spi: s3c64xx: fix printk warnings

Fix the following build warnings when LPAE is enabled:

drivers/spi/spi-s3c64xx.c:1466:2: warning: format '%x' expects argument of type 'unsigned int', but argument 4 has type
'resource_size_t' [-Wformat]
drivers/spi/spi-s3c64xx.c:1466:2: warning: format '%x' expects argument of type 'unsigned int', but argument 5 has type
'resource_size_t' [-Wformat]

Use vsprintf extension %pR to format resource.
