[ Upstream commit 2326828ee40357b3d2b1359b8ca7526af201495b ]

The following build warnings are seen when building for ARM64 allmodconfig:

drivers/crypto/mxc-scc.c:181:20: warning: format '%d' expects argument of type 'int', but argument 5 has type 'size_t' {aka 'long unsigned int'} [-Wformat=]
drivers/crypto/mxc-scc.c:186:21: warning: format '%d' expects argument of type 'int', but argument 4 has type 'size_t' {aka 'long unsigned int'} [-Wformat=]
drivers/crypto/mxc-scc.c:277:21: warning: format '%d' expects argument of type 'int', but argument 4 has type 'size_t' {aka 'long unsigned int'} [-Wformat=]
drivers/crypto/mxc-scc.c:339:3: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
drivers/crypto/mxc-scc.c:340:3: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

Fix them by using the %zu specifier to print a size_t variable and using
a plain %x to print the result of a readl().
