Add the PMU bootloader generator and PMU LS ops that will enable proper
PMU operation if the PMU falcon is designated as managed.

As different firmare versions use different HS descriptor formats, we
need to abstract this part as well.

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

Offsets were not properly computed. This went unnoticed because we are
only using one app for now.

Perform the zeroing of BL descriptors in the caller function instead of
trusting each generator will do it. This could avoid a few pulled hairs.

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.

Add a flag that can be set when declaring how a LS firmware should be
loaded. This allows us to remove falcon-specific code in the loader.

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.
