Now that we don't need struct_mutex in the free path, we can get rid of
the asynchronous free all together.

[samtran@codeaurora.org: avoid changes related to debugfs and shrinker]
Signed-off-by: Samantha Tran <samtran@codeaurora.org>
We use a llist and a worker to delay the object cleanup. This avoids
taking mmap_sem and struct mutex in the wrong order when calling
drm_gem_object_put-unlocked() from drm_gem_mmap().
Fixes lockdep problem with copy_from_user() in msm_ioctl_gem_submit().

Currently, SDE_DBG_DUMP takes any number of hw block names along with
few defined strings as arguments. This set of arguments is used to
determine which HW block registers needs to be dumped. Move to a
blk bitmask to avoid passing a large set of arguments. The bitmask is
split based on the clks required to access the HW block for ease of use.
The lower 0-23 bits are used for HW blocks which can be accessed by just
enabling the MDP clks. DP is kept separate as it needs DP specific
clks to be enabled. Add a debugfs node through which the mask can be
modified, which can be useful while using the debugfs dump option to
force a panic.
As part of the change, remove in-log/in-mem enable mask debugfs node
for every debugbus and use a single node to control the logging
mechanism for all the HW blocks debugbus.
