The `q35-alpine.cfg` adds a lot of PCIe devices to resemble the
topology inside an Intel Alpine Ridge Thunderbolt controller.
By no means could this be detected as such a controller. But
having a real-world example of such a topology can help to
test the allocator and other algorithms on a deeper tree.
It adds two levels of PCIe switches (`alpine-root` and
`alpine-1`), and two endpoints (a `pci-testdev` and an xHCI
controller).
It can be added to the default `q35-base.cfg` config, e.g.
with:
$ make qemu QEMU_EXTRA_CFGS=util/qemu/q35-alpine.cfg

CB:49896 added support in `intel_microcode_find()` to cache the found
microcode for faster subsequent accesses. This works okay when the
function succeeds in finding the microcode on BSP. However, if for any
reason, `cpu_microcode_blob.bin` does not contain a valid microcode
for the given processor, then the logic ends up attempting to find
microcode again and again every time it is called (because
`ucode_updates` is set to NULL on failed find, thus retriggering the
whole find sequence every time). This leads to a weird race condition
when multiple APs are running in parallel and executing this
function.
A snippet of the issues observed in the scenario described above:
```
...
microcode: Update skipped, already up-to-date
...
Microcode header corrupted!
...
```
1. AP reports that microcode update is being skipped since the current
version matches the version in CBFS (even though there is no matching
microcode update in CBFS).
2. AP reports microcode header is corrupted because it thinks that the
data size reported in the microcode is larger than the file read from
CBFS.
Above issues occur because each time an AP calls
`intel_microcode_find()`, it might end up seeing some intermittent
state of `ucode_updates` and taking incorrect action.
This change fixes this race condition by separating the logic for
finding microcode into an internal function `find_cbfs_microcode()`
and maintaining the caching logic in `intel_microcode_find()` using a
boolean flag `microcode_checked`.
BUG=b:182232187
TEST=Verified that `intel_microcode_find()` no longer makes repeated
attempts to find microcode from CBFS if it failed the first time.

UART pad configuration should not be done in common code, because that
may cause short circuits, when the user sets a wrong UART index. Thus,
add the corresponding pads to the early UART gpio table for the board as
a first step. Common UART pad config code then gets dropped in CB:48829.
Also switch to `bootblock_mainboard_early_init` to configure the pads in
early bootblock before console initialization, to make the console work
as early as possible. The board does not do any other gpio configuration
in bootblock, so this should not influence behaviour in a negative way
(e.g. breaking overrides).

Configuring touch controllers to use edge-triggered interrupts is not
recommended as it is very easy to lose an edge when kernel drivers
disable the interrupt for one reason or another, and recovering from
this condition requires workarounds in the kernel.
Unfortunately the example setting up a touchpad used edge-triggered
interrupts, and this set up has been propagating through the boards.
Let's switch the example to use level interrupts instead.
