hw/char/serial currently contains the implementation of both TYPE_SERIAL and
TYPE_SERIAL_MM. According to serial_class_init(), TYPE_SERIAL is an internal
class while TYPE_SERIAL_MM is used by numerous machine types directly. Let's
move the latter into its own module which makes the dependencies more obvious
and the code more tidy.
The includes and the dependencies have been converted mechanically except in the
hw/char directories which were updated manually. The result was compile-tested.
Now, only hw/char makes direct use of TYPE_SERIAL:
# grep -r -e "select SERIAL" | grep -v SERIAL_
hw/char/Kconfig: select SERIAL
hw/char/Kconfig: select SERIAL
hw/char/Kconfig: select SERIAL
hw/char/Kconfig: select SERIAL
hw/char/Kconfig: select SERIAL
# grep -r -e "/serial\\.h"
include/hw/char/serial-mm.h:#include "hw/char/serial.h"
hw/char/serial-pci-multi.c:#include "hw/char/serial.h"
hw/char/serial.c:#include "hw/char/serial.h"
hw/char/serial-isa.c:#include "hw/char/serial.h"
hw/char/serial-pci.c:#include "hw/char/serial.h"

Add the basic infrastructure (register read/write, type...)
to implement the STM32L4x5 USART.
Also create different types for the USART, UART and LPUART
of the STM32L4x5 to deduplicate code and enable the
implementation of different behaviors depending on the type.

Commit a8fb0a500a ("hw/char: Add Microchip PolarFire SoC MMUART
emulation") added a dependency on the SERIAL model, but forgot to
add the Kconfig selector.
Add the dependency to the MCHP_PFSOC_MMUART symbol to fix when
building the MICROCHIP_PFSOC machine stand-alone:

These were designed to facilitate testing but should provide enough
function to be useful in other contexts. Only a subset of the functions
of each peripheral is implemented, mainly due to the lack of a standard
way to handle electrical connections (like GPIO pins).

Instead of including the same list of devices for each target,
set CONFIG_PCI to true, and make the devices default to present
whenever PCI is available. However, s390x does not want all the
PCI devices, so there is a separate symbol to enable them.
Done mostly with the following script:
while read i; do
i=${i%=y}; i=${i#CONFIG_}
sed -i -e'/^config '$i'$/!b' -en \
-e'a\' -e' default y if PCI_DEVICES\' -e' depends on PCI' \
`grep -lw $i hw/*/Kconfig`
done < default-configs/pci.mak
followed by replacing a few "depends on" clauses with "select"
whenever the symbol is not really related to PCI.

sed -i '$d' hw/*/Kconfig
for i in hw/*; do
if test -d $i && ! test -f $i/Kconfig; then
touch $i/Kconfig
git add $i/Kconfig

done
Whenever a symbol is referenced from multiple subdirectories, the
script prints the list of directories that reference the symbol.
These symbols have to be added manually to the Kconfig files.
Kconfig.host and hw/Kconfig were created manually.
