[PATCH 0/2] nova-core: add initial support for gpu timer (v2)

[Dave Airlie via B4 Relay <devnull+airlied.redhat.com@kernel.org>]

The GPU has a timer, one of the pieces of information
we need to pass into GSP init later is the timer offset.
    
This series just adds support for setting up the timer
on Turing+, with hals for Turing and Hopper.
    
Right now it calculates the value to send to GSP but
the code to send it will be added later.
    
For some hardware variants sending a proper value
is required for GSP init to succeed.

v2 changes on second patch.
