Stefan Agner a89eb89b38 imx: mx7: psci: provide complete PSCI 1.0 implementation 
PSCI 1.0 require PSCI_VERSION, PSCI_FEATURES, AFFINITY_INFO and
CPU_SUSPEND to be implemented. Commit 0ec3d98f76 ("mx7_common:
use psci 1.0 instead of 0.1") marked the i.MX 7 implementation to
be PSCI 1.0 compliant but failed to implement those functions.
Especially the missing PSCI version callback was noticeable when
booting Linux:

  [    0.000000] psci: probing for conduit method from DT.
  [    0.000000] psci: PSCIv65535.65535 detected in firmware.
  [    0.000000] psci: Using standard PSCI v0.2 function IDs
  [    0.000000] psci: MIGRATE_INFO_TYPE not supported.
  [    0.000000] psci: SMC Calling Convention v1.0

This patch provides a minimal implementation thereof. With this
patch applied Linux detects PSCI 1.0:

  [    0.000000] psci: probing for conduit method from DT.
  [    0.000000] psci: PSCIv1.0 detected in firmware.
  [    0.000000] psci: Using standard PSCI v0.2 function IDs
  [    0.000000] psci: MIGRATE_INFO_TYPE not supported.
  [    0.000000] psci: SMC Calling Convention v1.0

Fixes: 0ec3d98f76 ("mx7_common: use psci 1.0 instead of 0.1")
