[PATCH] dma: ste_dma: Fix warning when CONFIG_ARM_LPAE=y

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <fabio.estevam@freescale.com>

When CONFIG_ARM_LPAE=y the following build warning are generated:

drivers/dma/ste_dma40.c:3228:2: warning: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'resource_size_t' [-Wformat]
drivers/dma/ste_dma40.c:3582:3: warning: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'resource_size_t' [-Wformat]
drivers/dma/ste_dma40.c:3582:3: warning: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'resource_size_t' [-Wformat]
drivers/dma/ste_dma40.c:3593:5: warning: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'resource_size_t' [-Wformat]

According to Documentation/printk-formats.txt '%pa' can be used to properly 
print 'resource_size_t'.

Also, for printing memory region the '%pr' is more convenient.
