gpu: nvgpu: Always initialize system vm

PMU, FECS and GPCCS use the same address space. We used to initialize
the address space only if PMU is enabled. Create the system address
space always.

FECS and GPCCS used to have slower bit bang and faster DMA method
for loading ucode. Slower method is needed when FECS and GPCCS do not
have an address space. Remove the slower method as not anymore
needed.
