Shankari Anand d234f3aef5 gpu: nova-core: Update ARef imports from sync::aref
Update call sites in nova-core to import `ARef`
from `sync::aref` instead of `types`.

This aligns with the ongoing effort to move `ARef` and
`AlwaysRefCounted` to sync.

[acourbot@nvidia.com: use standard prefix for nova-core.]

Alexandre Courbot 3606620b31 gpu: nova-core: update and annotate TODO list
A few new dependencies are required to remove some of the TODO items:

- A way to safely convert from byte slices to types implementing
  `FromBytes`,
- A way to obtain slices and write into a `CoherentAllocation`,
- Several improvements to the `register!()` macro,
- Alignment operations to powers of two, and an equivalent to the C
  `fls`,
- Support for `xa_alloc` in the XAlloc bindings.

Some items have also become obsolete:

- The auxiliary bus abstractions have been implemented and are in use,
- The ELF utilities are not considered for being part of the core kernel
  bindings anymore.
- VBIOS, falcon and GPU timer have been completed.

We now have quite a few TODO entries in the code, so annotate them with
a 4 letter code representing the corresponding task in `todo.rst`. This
allows to easily find which part of the code corresponds to a given
entry (and conversely).

Alexandre Courbot 80213934d0 gpu: nova-core: compute layout of the FRTS region
FWSEC-FRTS is run with the desired address of the FRTS region as
parameter, which we need to compute depending on some hardware
parameters.

Do this in a `FbLayout` structure, that will be later extended to
describe more memory regions used to boot the GSP.

Alexandre Courbot 6554ad65b5 gpu: nova-core: register sysmem flush page
Reserve a page of system memory so sysmembar can perform a read on it if
a system write occurred since the last flush. Do this early as it can be
required to e.g. reset the GPU falcons.

Chipsets capabilities differ in that respect, so this commit also
introduces the FB HAL.

[ * Use kernel::page::PAGE_SIZE instead of kernel::bindings::PAGE_SIZE.
  * Get rid of the Option for SysmemFlush.
  * Slightly reword SysmemFlush doc-comments.
