gpu: nvgpu: p-state bound arbiter
Modification of the ARBITER clocks to be P-State aware
Up to now the arbiter just considered the whole range
of the GPC and MCLK domains, which could end up on
illegal combinations of MCLK, GPC2CLK, and set the
SYSCLK and XBARCLK domains below their minimum VCO
The following has been implemented:
(1) Modified VF tables to add which PState are
supported on each point.
(2) Return and store the current PState on the
arbiter state.
(3) Modified logic to prevent illegal combinations of
MCLK and GPC2CLK.
(4) Modified logic to prevent setting VF points for
XBAR and SYS domains below VCO limits.
(5) Modified voltage calculation to account for increased
values of XBAR and SYS on some VF points.
(6) Modified arbiter clock target logic to prevent an
application that has not requested a particular VF point
to set target to default targets.
(7) Remove unnecesary mutexes from critical path
