Implement the H_SVM_INIT_ABORT hcall which the Ultravisor can use to abort an SVM after it has issued the H_SVM_INIT_START and before the H_SVM_INIT_DONE hcalls. This hcall could be used when Ultravisor encounters security violations or other errors when starting an SVM. Note that this hcall is different from UV_SVM_TERMINATE ucall which is used by HV to terminate/cleanup an VM that has becore secure. The H_SVM_INIT_ABORT basically undoes operations that were done since the H_SVM_INIT_START hcall - i.e page-out all the VM pages back to normal memory, and terminate the SVM. (If we do not bring the pages back to normal memory, the text/data of the VM would be stuck in secure memory and since the SVM did not go secure, its MSR_S bit will be clear and the VM wont be able to access its pages even to do a clean exit). Based on patches and discussion with Paul Mackerras, Ram Pai and Bharata Rao.
