soc/tegra: Changes for v5.2-rc1

Besides a couple of fixes to better cope with deferred probing, this set
of patches also implements the acquire/release protocol for resets used
during powergate operations. This is necessary to allow these resets to
be temporarily shared with other devices that may also need to control
these resets.

drm/tegra: Changes for v5.2-rc1

This contains a fix for the usage of shared resets that previously
generated a WARN on boot. In addition, there's a fix for CPU cache
maintenance of GEM buffers allocated using get_pages().

There are cases where a driver needs explicit control over a reset line
that is exclusively conneted to its device, but this control has to be
temporarily handed over to the power domain controller to handle reset
requirements during power transitions.
Allow multiple exclusive reset controls to be requested in 'released'
state for the same physical reset line, only one of which can be
acquired at the same time.

Reset controller changes for v5.1

This adds the include/linux/reset directory to MAINTAINERS for reset
specific headers and adds headers for sunxi and socfpga in there to
get rid of a few extern function declarations.
There is a new reset driver for the Broadcom STB reset controller and
the i.MX7 system reset controller driver is extended to support i.MX8MQ
as well. Finally, there is a new header with reset id constants for
the Meson G12A SoC, which has a reset controller identical to Meson AXG
and thus can reuse its driver and DT bindings.
