fd29183901 elk: Use F16TO32 for nir_op_f2f32 of float16 source 
This matches the behavior of nir_op_unpack_half_2x16_split_x. Gfx7
uses a special opcode for this conversion. Fixes numerous assertion
failures in shader-db on Ivy Bridge and Haswell.

I am not sure why this was never encountered previously.

013b21d52f nvk,nak: Store offsets in a const extern struct 
Move some of this constant data out of fs_key and into a constant
struct. This reduces the size of the fs_key and gives us a spot to add
additional non-fs offsets like printf buffers.

Passing this through a const global may be a little odd but it has the
benefit that we don't need to hash the offsets as additinal state
relevant to a compilation, since they can never change without
a modification to the binary.

89e42a01dd broadcom/ci: fetch custom packaged kernel in CI-Tron 
Unfortunately RPi firmware does not contain the latest available kernel
deployed in Raspberry Pi OS.

So for now, we create a custom version by just packaging manually the
kernel distributed in the official OS.

It is worth to note that Raspberry Pi OS  does not contain a 32-bit
kernel for rpi4 or rpi5 (it does for rpi3). Instead, they use the 64-bit
kernel but then use 32-bit userland.
