Now that two real additional passes are performed in case of extra pass
requested by BPF core, padding is not needed anymore except during
initial pass done before memory allocation to count maximum possible
program size.
So, only do the padding when 'image' is NULL.
Signed-off-by:
BPF progs are never called with more than one argument, plus the
tail call count as a second argument when needed.
So, no need to retrieve 9th and 10th argument (5th 64 bits argument)
from the stack in prologue.

Just like PPC64, implement bpf_has_stack_frame() and only sets the frame
when needed.
The difference with PPC64 is that PPC32 doesn't have a redzone, so
the stack is required as soon as non volatile registers are used or
when tail call count is set up.

r4 is cleared at function entry and used as tail call count.
But when the function does not perform tail call, r4 is

I think patches 1 and 2 could be a single patch.
I'm having hard time understanding how things are built. Patch 3
introduces 273 lines of new code in a file named p2020.c while only
removing
/21/221 . He re-iterated the same view
recently in https://lkml.org/lkml/2022/10/12/622
So test !irq instead of tesing irq == NO_IRQ.
All other usage of NO_IRQ for powerpc were remove in previous cycle
so time has come to remove NO_IRQ completely for powerpc.
