gpu: nvgpu: enable/disable tegra fuse clock
GPU hardware block needs tegra fuse clock to mirror
gpu fuses from tegra fuses to gpu domain.
Tegra fuse driver provided following APIs to
enable/disable tegra fuse clock:
int tegra_fuse_clock_enable(void);
int tegra_fuse_clock_disable(void);
To ensure that tegra fuse clock is disabled by nvgpu
driver when gpu hardware block is not in use by:
Calling tegra_fuse_clock_enable() while doing
gk20a_pm_unrailgate() and calling
tegra_fuse_clock_disable() while doing
gk20a_pm_railgate().
