firmware/psci: fix application of sizeof to pointer

commit 2ac5fb35cd520ab1851c9a4816c523b65276052f upstream.

sizeof when applied to a pointer typed expression gives the size of
the pointer.

./drivers/firmware/psci/psci_checker.c:158:41-47: ERROR application of sizeof to pointer

This issue was detected with the help of Coccinelle.
