Enable the Mali GPU in the Turing RK1.
This patch also sets the external GPU voltage regulator in the RK806-1
to "always-on" because it is necessary for this regulator to be active
when enabling the GPU power domain or the kernel will fail with:
rockchip-pm-domain fd8d8000.power-management:power-controller: \
failed to set domain 'gpu', val=0
rockchip-pm-domain fd8d8000.power-management:power-controller: \
failed to get ack on domain 'gpu', val=0x1bffff
...followed by a panic when it attempts to access unavailable QoS
registers.
Since there is currently no `domain-supply` or similar to express this
dependency, the only way to ensure that the regulator is never off when
the GPU power domain is brought up is to ensure that the regulator is
never off.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
