adcb5ea53d hv: Not to destroy ept of trusty memory if it's not initialized.
If guest reboot is issued before trusty init hypercall is issued,
we shouldn't destroy ept fo trusty memory because the ept is not
created yet.

fd6a0d8c9b add IO requrest 'req_buf' check before reference
This address maybe invalid if a hostile address was set
in hypercall 'HC_SET_IOREQ_BUFFER'.it should be validated
before using.

Update:
  -- save HVA to guest OS's request buffer in hyperviosr
  -- change type of 'req_buf' from 'uint64_t' to 'void *'
  -- remove HPA to HVA translation code when using this addr.
  -- use error number instead of -1 when return error cases.

Before this patch, guest temporary page tables were generated by hardcode

and create page tables to cover new range(511G~511G+16M) with trusty
requirement.
