In host1x_syncpt_wait(), the hardware syncpoint value was loaded
initially for expiry check, and then loaded a second time to
populate the caller's value pointer. Reuse a single load for
both purposes.
After dma_fence_wait_timeout(), the previous code reloaded the syncpoint
value for the expiry check, which is only required in the timeout case.
On success (i.e., return value > 0, or return value == 0 with zero
jiffies remaining), the ISR has already cached the value before
signaling the fence. The value pointer can therefore be populated using
the cached value using host1x_syncpt_read_min() without MMIO access.
Only the timeout path requires a fresh load, move host1x_syncpt_load()
under that path.
Measured Syncpoint wait latency (50000 samples):
Average latency: 12.2 us -> 10.6 us
99.99 pct latency: 62.96 us -> 51.90 us

When a buffer object is pinned via host1x_bo_pin() with a cache, the
resulting mapping is kept in the cache so it can be reused on subsequent
pins. Each mapping held a reference to the underlying host1x_bo (taken
in tegra_bo_pin / gather_bo_pin), so as long as a mapping was cached,
the bo itself could not be freed.
However, the only way to remove the cached mapping was through the free
path of the buffer object. This meant that if a bo got cached, it could
never get freed again.
Resolve the circularity by holding a weak reference to the bo from the
cache side. This is done by having the .pin callbacks not bump the bo's
refcount -- instead the common Host1x bo code does so, except for the
cache reference.
Also move the remove-cache-mapping-on-free code into a common function
inside Host1x code. This is only called from the TegraDRM GEM buffers
since those are the only ones that can be cached at the moment.

The "gems" debugfs file is getting a little too wide for comfort. While
a lot of this is unavoidable due to the theoretical upper limits of
numbers here (e.g. size needs to be 16 chars because 2**48-1 in decimal
is 15 digits, plus one space for separation), the refcount column has a
decent 5 characters to be saved, as it can only ever contain a 10-digit
decimal number.
Reduce the refcount column's width to 11, which fulfils this requirement
with an additional space for separation.

For fdinfo to be able to fill its evicted counter with data, panthor
needs to keep track of whether a GEM object has ever been reclaimed.
Just checking whether the pages are resident isn't enough, as newly
allocated objects also won't be resident.
Do this with a new atomic_t member on panthor_gem_object. It's increased
when an object gets evicted by the shrinker, and saturates at INT_MAX.
This means that once an object has been evicted at least once, its
reclaim counter will never return to 0.
Due to this, it's possible to distinguish evicted non-resident pages
from newly allocated non-resident pages by checking whether
reclaimed_count is != 0
Also add a new column and status flag to the panthor gems debugfs: the
column is the number of times an object has been evicted, whereas the
flag indicates whether it currently is evicted.
