Merge remote-tracking branch 'remotes/alistair/tags/pull-riscv-to-apply-20200910' into staging

This PR includes multiple fixes and features for RISC-V:
- Fixes a bug in printing trap causes
- Allows 16-bit writes to the SiFive test device. This fixes the
failure to reboot the RISC-V virt machine
- Support for the Microchip PolarFire SoC and Icicle Kit
- A reafactor of RISC-V code out of hw/riscv

hw/sd: Add Cadence SDHCI emulation

Cadence SD/SDIO/eMMC Host Controller (SD4HC) is an SDHCI compatible
controller. The SDHCI compatible registers start from offset 0x200,
which are called Slot Register Set (SRS) in its datasheet.

This creates a Cadence SDHCI model built on top of the existing
generic SDHCI model. Cadence specific Host Register Set (HRS) is
implemented to make guest software happy.

hw/sd/sdhci: Move PCI-related code into a separate file

Some machines have an SDHCI device, but no PCI. To be able to
compile hw/sd/sdhci.c without CONFIG_PCI, we must not call functions
like pci_get_address_space() and pci_allocate_irq() there. Thus
move the PCI-related code into a separate file.

This is required for the new Kconfig-like build system, e.g. it is
needed if a user wants to compile a QEMU binary with just one machine
that has SDHCI, but no PCI, like the ARM "raspi" machines for example.

build: convert pci.mak to Kconfig

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.

kconfig: introduce kconfig files

The Kconfig files were generated mostly with this script:

set fnord `git grep -lw $i -- 'hw/*/Makefile.objs' `
shift

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
fi
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.
