PSCI_VERSION and MIGRATE_INFO_TYPE_UP_CPU return unsigned values, with the latter returning a 64-bit value. However, the PSCI invocation functions have prototypes returning int. This patch upgrades the invocation functions to return unsigned long, with a new typedef to keep things legible. As PSCI_VERSION cannot return a negative value, the erroneous check against PSCI_RET_NOT_SUPPORTED is also removed. The unrelated psci_initcall_t typedef is moved closer to its first user, to avoid confusion with the invocation functions. In preparation for sharing the code with ARM, unsigned long is used in preference of u64. In the SMC32 calling convention, the relevant fields will be 32 bits wide.
