To make multi_v7_defconfig really "multi", let's add virtio drivers
to allow booting a default kernel as a KVM/QEMU guest.
MACH_VIRT is already defined, so we just add VIRTIO_BLK, VIRTIO_NET
and VIRTIO_CONSOLE to actually make this kernel useful in a guest.

Instead select CONFIG_LEDS_SYSCON and MFD_SYSCON, so we can

Add a defconfig covering all known pxa board, ie. all selectable machine
files in arch/arm/mach-pxa/*.c.

This defconfig was built by doing :
 - aggregation of all known defconfigs by cat
	am200epdkit_defconfig
	cm_x2xx_defconfig
	cm_x300_defconfig
	colibri_pxa270_defconfig
	colibri_pxa300_defconfig
	corgi_defconfig
	em_x270_defconfig
	eseries_pxa_defconfig
	ezx_defconfig
	h5000_defconfig
	imote2_defconfig
	lpd270_defconfig
	lubbock_defconfig
	magician_defconfig
	mainstone_defconfig
	multi_v7_defconfig
	palmz72_defconfig
	pcm027_defconfig
	pxa255-idp_defconfig
	pxa3xx_defconfig
	raumfeld_defconfig
	spitz_defconfig
	trizeps4_defconfig
	viper_defconfig
	xcep_defconfig
	zeus_defconfig
 - manual make menuconfig to ensure :
   - all pxa implementation were selected
   - all drivers were transformed into modules rather than builtin
     => as a consequence this single kernel will rely on an initramfs
     => as kernel size matters on pxa, each machine can take the subset
        of modules required for it to work
   - all missed configurations are selected verified by :
     => grep -i pxa .config | grep "is not set"
     => this should only show the left on purpose options (either not
        selectable or sharpsl exception below)
 - CONFIG_PXA_SHARPSL was disabled
   This breaks the boot very early on any non Sharp platform, see
   head-sharpsl.S

This defconfig was tested as booting up to the login phase on :
 - lubbock (pxa25x)
 - mainstone (pxa27x)
 - zylonite (pxa3xx)

The completion of this work will require to :
 - parse manually all the arch/arm/mach-pxa/*c files, look for all
   platform devices added, and verify they are all in pxa_defconfig
 - do the same to ensure all pxa specific drivers (leds, gpio, ...) are
   included

Commit 69fb4dca ("power: Add an axp20x-usb-power driver") introduced a
new driver for the USB power supply used on various Allwinner based SBCs.
However, the driver was not added to multi_v7_defconfig which breaks USB
support for some boards (e.g. LeMaker BananaPi) as the kernel will now
turn off the USB power supply during boot by default if the driver isn't
present. (This was not the case in linux 4.3 or lower where the USB power
was always left on.)

Hence, add the driver to multi_v7_defconfig in order to keep USB support
working on those boards that require it.

- Enable the I2C driver

- Enable the RTC driver for DS1338 as found on the Versatile

- Compile in the MMCI MMC driver, which is good if you

The debug-ll infrastructure can be configured in two ways, either
by selecting a platform specific debug option, or by picking one
of the generic options (8250 or pl01x typically). For compatibility
with multiplatform kernels, we have changed a couple of platforms
to use the former method now when they used to use the latter.

Unfortunately, this broke the defconfigs because now they still
enable CONFIG_DEBUG_LL_UART_PL01X or CONFIG_DEBUG_LL_UART_8250,
and we no longer configure the correct register addresses
automatically.

Embarrassingly, this was only found in linux-next when the
defconfig builds turned up errors for multiple people, and I
had not caught those in my own tests, which were done using
the randconfig fixes patchset on top, and that has a workaround
to avoid a build error when the addresses are not configured.

The error was something like:

.config:2010:warning: symbol value '' invalid for DEBUG_UART_PHYS
.config:2011:warning: symbol value '' invalid for DEBUG_UART_VIRT

This patch avoids the problem by removing the respective
statements from the defconfig files. Any out of tree defconfig
files on the platforms I have changed will have to do the same
change or run into the build error above. Any users that have
a full .config already set the correct DEBUG_UART_PHYS/VIRT
addresses and do not need to change anything.
