stm class/intel_th: Updates for 4.10

These are:
  * Fix for an error-path leak in stm
  * Host-driven mode in intel_th
  * Documentation and other small updates

Signed-off-by: Alexander Shishkin <alexander.shishkin@linux.intel.com>

When detecting host debugger mode either though a module option or via
the scratchpad register, do not export any configuration or capture
related attributes to userspace and refuse attempts by the output drivers
to configure output ports.

This way, GTH can still act as a hub and ensure that the other components
that rely on its presence continue to function properly, namely the
source devices.

This patch adds a 'host_mode' module option to enable host-driven
operational mode in the driver. In this mode, the driver does not
perform trace configuration or enable trace capture, but still
provides all the means necessary for software trace sources to
write their data to the Trace Hub. This means that the debug host
takes care of all the configuration and enabling and we do not
interfere.

 "This contains two patches fixing problems with my patch series meant

  The last patch on this series is actually not related to DMA on stack.
  It solves a longstanding bug affecting module unload, causing
  module_put() to be called twice. It was reported by the user who
  reported and tested the issues with the gp8psk driver with the DMA
  fixup patches. As we're late at -rc cycle, maybe you prefer to not
  apply it right now. If this is the case, I'll add to the pile of

The ns->lba_shift assumes its value to be the logarithmic of the
LA size. A previous patch duplicated the lba_shift calculation into
lightnvm. It prematurely also subtracted a 512byte shift, which commonly
is applied per-command. The 512byte shift being subtracted twice led to
data loss when restoring the logical to physical mapping table from
device and when issuing I/O commands using rrpc.

Fix offset by removing the 512byte shift subtraction when calculating
lba_shift.
