[PATCH 0/2] firmware: stratix10-svc: fix kaddr dangling pointers and populate kaddr1

[Adrian Ng Ho Yin <adrian.ho.yin.ng@altera.com>]

kaddr1/2/3 in the stratix10 service layer are set to addresses of local
arm_smccc_res fields that go out of scope when the setting function returns,
leaving dangling pointers in the callback data.

Patch 1 fixes this by adding a1/a2/a3 scratch fields to struct
stratix10_svc_cb_data, which lives for the SVC thread lifetime, and
pointing kaddrN to those fields instead of the stack.

Patch 2 uses the same mechanism to populate the previously unset kaddr1 in
svc_thread_cmd_config_status(), exposing firmware status details to callers.
