Add infrastructure to track statistics for GPU submissions
by sampling certain perfcounters before and after a submission.
To store the statistics, the per-ring memptrs region is
expanded to include room for up to 64 entries - this should
cover a reasonable amount of inflight submissions without
worrying about losing data. The target specific code inserts
PM4 commands to sample the counters before and after
submission and store them in the data region. The CPU can
access the data after the submission retires to make sense
of the statistics and communicate them to the user.

suspend_state field of dpu_kms as well.

Since we found a problem with the 'copy-from' operation after objects have
been truncated, offloading object copies to OSDs should be discouraged
until the issue is fixed.
Thus, this patch adds the 'nocopyfrom' mount option to the default mount
options which effectily means that remote copies won't be done in
copy_file_range unless they are explicitly enabled at mount time.
[ Adjust ceph_show_options() accordingly. ]

We need to add mcasp l3 port ranges for mcasp to use a correct l3
data port address for dma. And we're also missing the optional clocks
that we have tagged with HWMOD_OPT_CLKS_NEEDED in omap_hwmod_7xx_data.c.
Note that for reading the module revision register HWMOD_OPT_CLKS_NEEDED
do not seem to be needed. So they could be probably directly managed
only by the mcasp driver, and then we could leave them out for the
interconnect target module.

Looks like I missed the ranges for am335x epwmss. Let's set it up the
same way as for am437x and dra7.

The md->wait waitqueue is used by both bio-based and request-based DM.
Commit dbd3bbd291 ("dm rq: leverage blk_mq_queue_busy() to check for
outstanding IO") lost sight of the requirement that
dm_wait_for_completion() must work with all types of DM devices.
Fix md_in_flight() to call the blk-mq or bio-based method accordingly.
