In cases where a kernel channel dies, we can reload the context by
just reloading the golden context buffer. This patch makes necessary
infrastructural changes to support this behaviour.

All channels in a TSG need to share same engine context
i.e. pointer in RAMFC of all channels in a TSG must point
to same NV_RAMIN_GR_WFI_TARGET
To get this, add a pointer to gr_ctx inside TSG struct so
that TSG can maintain its own unique gr_ctx
Also, change the type of gr_ctx in a channel to pointer
variable so that if channel is part of TSG it can point
to TSG's gr_ctx otherwise it will point to its own gr_ctx
In gk20a_alloc_obj_ctx(), allocate gr_ctx as below :
1) If channel is not part of any TSG
- allocate its own gr_ctx buffer if it is already not allocated
2) If channel is part of TSG
- Check if TSG has already allocated gr_ctx (as part of TSG)
- If yes, channel's gr_ctx will point to that of TSG's
- If not, then it means channels is first to be bounded to
this TSG
- And in this case we will allocate new gr_ctx on TSG first
and then make channel's gr_ctx to point to this gr_ctx
Also, gr_ctx will be released as below ;
1) If channels is not part of TSG, then it will be released
when channels is closed
2) Otherwise, it will be released when TSG itself is closed

Allocate dummy secure buffer of size PAGE_SIZE during gk20a_probe().
This will also help to initiate first secure memory (VPR)
resize call while GPU is rail gated and in reset.
This dummy buffer is released after we allocate some more
secure memory buffers in alloc_global_ctx_buffers()

Rewrite PMU boot sequence as a state machine. At PMU power-up send
initial messages, and reset state machine. At each reply from PMU,
do the next stage of PMU boot and set state.
As now PMU and FECS boot are independent, we need to ensure engine
idle before saving ZBC.

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.
