6433963801 gpu: nvgpu: clean up ctx_vars properly
Set ctx_vars.valid to false when removing support.  Otherwise a
re-poweron sequence could crash when the flag wouldn't match the real
state of the driver.

Also free all allocated regs instead of leaking some of them.

30d399de30 gpu: nvgpu: load secure gpccs using dma
bug 200080684

use new cmd defined in ucode for loading
GR falcons. flip PRIV load flag in lsb
header to indicate using dma. use pmu msg
as cmd completion for new cmd instead of
polling fecs mailbox. also move
check for using dma in non secure boot path
to hal.
