sched.ready is nothing with ring initialization, it needs to set
to be true after ring/IB test in amdgpu_ring_test_helper to tell
the ring is ready for submission.

<id>1c6d567bdf73a207f51ef2e5745854ba7daa22c7</id>
<content type='text'>
Generate HW IP's sched_list in amdgpu_ring_init() instead of
amdgpu_ctx.c. This makes amdgpu_ctx_init_compute_sched(),
ring.has_high_prio and amdgpu_ctx_init_sched() unnecessary.
This patch also stores sched_list for all HW IPs in one big
array in struct amdgpu_device which makes amdgpu_ctx_init_entity()
much more leaner.

v2:
fix a coding style issue
do not use drm hw_ip const to populate amdgpu_ring_type enum

v3:
remove ctx reference and move sched array and num_sched to a struct
use num_scheds to detect uninitialized scheduler list

v4:
use array_index_nospec for user space controlled variables
fix possible checkpatch.pl warnings
