H A Dthread_spmc.cb59e43fec4b57baee296cb3b8d54920ffe275589 Fri Dec 01 13:58:13 UTC 2023 Jens Wiklander <jens.wiklander@linaro.org> core: ffa: fix FFA_NOTIFICATION_GET vm_id

handle_notification_get() has until now read the receiver endpoint ID
from the upper 16 bits of w1, but the receiver endpoint ID is passed in
the lower 16 bits of w1 passed to FFA_NOTIFICATION_GET. So fix the
function to read the lower 16 bits instead.
