Return when !AMD and !HYGON is the right thing to do. No point in checking
device ids which cannot happen in the first place.

locking/rtmutex: Don't initialize lockdep when not required
pi_mutex isn't supposed to be tracked by lockdep, but just
passing NULLs for name and key will cause lockdep to spew a
warning and die, which is not what we want it to do.
Skip lockdep initialization if the caller passed NULLs for
name and key, suggesting such initialization isn't desired.

x86/mm: Expand static page table for fixmap space
We met a kernel panic when enabling earlycon, which is due to
the fixmap address of earlycon is not statically setup.
Currently the static fixmap setup in head_64.S only covers 2M
virtual address space, while it acutually could be in 4M space
with different kernel configurations.
So increase the static space to 4M for now by defining FIXMAP_PMD_NUM
to 2, and add a build time check for future possible overflow so that
the macro could be increased accordingly.
