Adapt the dl->body0 object to use an object from the body pool. This
greatly reduces the pressure on the TLB for IPMMU use cases, as all of
the lists use a single allocation for the main body.
The CLU and LUT objects pre-allocate a pool containing three bodies,
allowing a userspace update before the hardware has committed a previous
set of tables.
Bodies are no longer 'freed' in interrupt context, but instead released
back to their respective pools. This allows us to remove the garbage
collector in the DLM.

Adopt the SPDX license identifier headers to ease license compliance
management. All files in the driver are licensed under the GPLv2+ except
for the vsp1_regs.h file which is licensed under the GPLv2. This is
likely an oversight, but fixing this requires contacting the copyright
owners and is out of scope for this patch.
While at it fix the file descriptions to match file names where copy and
paste error occurred.
