A LS post-run hook can meet an error meaning the failure of secure boot.
Make sure this can be reported.

Having access to the secboot instance loading a LS firmware can be
useful to LS firmware handlers. At least more useful than just having an
out-of-context subdev pointer.
GP10B's firmware will also need to know the WPR address, which can be
obtained from the secboot instance.

Allow secboot to load a LS PMU firmware. LS PMU is one instance of
firmwares based on the message queue mechanism, which is also used for
other firmwares like SEC, so name its source file accordingly.

This allows the bootloader descriptor generation code to not rely on
specialized ls_ucode_img structures, making it reusable in other
instances.

The WPR and LSB headers, used to generate the LS blob, may have a
different layout and sizes depending on the driver version they come
from. Abstract them and confine their use to driver-specific code.

ucode_header is not used anywhere, so just get rid of it.

Split the act of building the ACR blob from firmware files from the rest
of the (chip-dependent) secure boot logic. ACR logic is moved into
acr_rxxx.c files, where rxxx corresponds to the compatible release of
the NVIDIA driver. At the moment r352 and r361 are supported since
firmwares have been released for these versions. Some abstractions are
added on top of r352 so r361 can easily be implemented on top of it by
just overriding a few hooks.
This split makes it possible and easy to reuse the same ACR version on
different chips. It also hopefully makes the code much more readable as
the different secure boot logics are separated. As more chips and
firmware versions will be supported, this is a necessity to not get lost
in code that is already quite complex.
This is a big commit, but it essentially moves things around (and split
the nvkm_secboot structure into two, nvkm_secboot and nvkm_acr). Code
semantics should not be affected.
