Andrew Turner ed4c884f2e Check if the gettime runtime service is valid. ... The U-Boot efi runtime service expects us to set the address map before calling any runtime services. It will then remap a few functions to their runtime version. One of these is the gettime function. If we call into this without having set a runtime map we get a page fault. Add a check to see if this is valid in efi_init() so we don't try to use the possibly invalid pointer.
