drm/amdgpu: simplify reservation handling during buffer creation

By using ttm_bo_init_reserved instead of the manual initialization of
the reservation object, the reservation lock will be properly unlocked
and destroyed when the TTM BO initialization fails.

Actual deadlocks caused by the missing unlock should have been fixed
by "drm/ttm: never add BO that failed to validate to the LRU list",
superseding the flawed fix in commit 38fc4856ad98 ("drm/amdgpu: fix
a potential deadlock in amdgpu_bo_create_restricted()").

This change fixes remaining recursive locking errors that can be seen
with lock debugging enabled, and avoids the error of freeing a locked
mutex.

As an additional minor bonus, buffers created with resv == NULL and
the AMDGPU_GEM_CREATE_VRAM_CLEARED flag are now only added to the
global LRU list after the fill commands have been issued.

Task 1: add BO to global list anyway
Task 2: grabs hold of the BO, waits on its reservation lock

drm/amd/amdgpu: Update read_sensor calls to have size parameter (v3)

This update allows sensors to return more than 1 value and
indicates to the caller how many bytes are written.

The debugfs interface has been updated to handle reading all
of the values.  Simply seek to the enum value (multiplied
by 4) and then read as many bytes as the sensor provides.

(v2):  Don't set size to 4 before reading GPU_POWER
