The `find_resource` function will never return null (will die instead).
Given that the existing code gracefully handles null pointers already,
it is reasonable to replace these function calls with `probe_resource`.

Instead of checking whether the return value equals -1, just check if it
is negative. Some Azalia implementations already do it, but most do not.

Several changes[1][2] to the Linux kernel now enable ASPM/AER for the
rt8169 network driver, for which it was previously disabled. This,
coupled with the southbridge enabling AER for all PCIe devices, has
resulted in a large amount of AER timeout errors in the kernel log for
boards which utilize the rt8169 for on-board Ethernet (e.g., google/beltino).
While performance is not impacted, the errors do accumulate.
To mitigate this, guard AER enablement via Kconfig, select it by default
(as to maintain current default behavior), and allow boards which need
to disable it to do so (implemented in subsequent commits).
This implementation is derived from that in soc/intel/broadwell.
Test: build/boot google/beltino variants with AER disabled (CB:46136),
verify dmesg log free of AER timeout errors.

Both PCH types are very different, and mixing the code for both together
isn't useful. First of all, inline `pch_is_lp` to return a constant.
This allows the compiler to optimize out unused code, which results in
smaller executables. For the Asrock B85M Pro4, it's about 2.5 KiB less.
Subsequent commits will further split the southbridge code.

We can now factor out the essentially duplicated ME functions.
We include a .c file to preserve reproducibility. This is needed because
there are two different `mei_base_address` global variables, and we have
to access the same variables in order for builds to be reproducible.
The duplicate global in `me.c` and `me_8.x.c` will be completely gone
once this new `me_common.c` file becomes a standalone compilation unit.
We are wrapping some things in static inline functions, as they won't be
directly accessible anymore after moving to a separate compilation unit.
Tested with BUILD_TIMELESS=1, Asus P8Z77-V LX2 remains identical.
