Changes in v2:
 - simplify page allocation approach
 - switch to returning EFI_DEVICE_ERROR on ENOMEM
 - drop efi return value argument from setup_mm_hdr

One critical fix for the EFI StMM driver, one error return code
adjustment and two smaller cleanups.

Note that the suggestion to convert tee_shm_register_kernel_buf to take
pages instead of buffer addresses is not forgotten, just in the backlog.
I wanted to avoid that the critical fix has to wait for me finding time
to refactor the API as well.
