msm: camera_v2: Create jpeg debugfs

This fixes kmsg errors because jpeg debugfs creation fails. The
device is online for only a few millisecs so the real use of the
interface is questionable, thus a full fix in ion with a camera
subdir not nessecary.
ion: replace userspace handle cookies with idr

Userspace handles should not leak kernel virtual addresses to
userspace.  They have to be validated by looking them up in an
rbtree anyways, so replace them with an idr and validate them
by using idr_find to convert the id number to the struct
ion_handle pointer.

ion: don't use id 0 for handle cookie

ion userspace clients think that the cookie is a pointer, so they
use NULL to check if the handle has been initialized.  Set the first
id number to 1.

ion: add new ion_user_handle_t type for the user-space token

Declare new ion_user_handle_t type to contain the token returned to user-space.
This allows a 2-step migration of the user-space code to a new kernel header
first, then will allow us to change the definition of the ion_user_handle_type_t
to int without breaking the API.

ion: hold reference to handle after ion_uhandle_get

commit 1262ab1846cf76f7549c66ef709120dbfbe6d49f (ion: replace
userspace handle cookies with idr) broke the locking in ion.
The ION_IOC_FREE and ION_IOC_MAP ioctls were relying on
ion_handle_validate to detect the case where a call raced
with another ION_IOC_FREE which may have freed the struct
ion_handle.

Rename ion_uhandle_get to ion_handle_get_by_id, and have it
take the client lock and return with an extra reference to
the handle.  Make each caller put its reference once it
is done with the handle.

Also modify users of ion_handle_validate to continue to hold
the client lock after calling ion_handle_validate until
they are done with the handle, and warn if ion_handle_validate
is called without the client lock held.

ion: export a few handle-related APIs

There are a few APIs (ion_handle_put and ion_handle_get_by_id) that are
useful for implementing Ion extensions (e.g. custom ioctl
handlers). Remove the `static' to make these APIs available to other Ion
code.

ion: invalidate cache after zero'ing buffers even if uncached

Currently, we don't invalidate the cache if we're working with uncached
buffers. However, the memory for those mappings might actually be stale
in the cache since someone else might have touched it. Just invalidate
the cache for everyone, cached or uncached.

Without this change, corruption was observed on the display due to stale
data in graphics buffers from Ion.

gpu: ion: system_heap: add support for 2MB allocations

Enable 2MB (order 9) allocations from the system heap. This improves the
performance of some heavyweight use cases. The benefit is especially
large for use cases where the buffer is mapped into an IOMMU since we
can leverage the 2MB IOMMU page table mappings.
