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.

The Marvell WiFi-Ex driver tries to load a firmware on probe. So if the
driver is built-in and probed before a firmware is available, this is
not loaded and the chip does not work.

This happens for example if an initramfs isn't used since the driver is
probed before the root filesystem is mounted.

Change the default config since the driver isn't needed for machines to
boot and is more convenient to have it enabled as a module to avoid
requiring an initramfs or to have the firmware built into the kernel.

The simplefb driver allows the kernel to render on a pre-allocated
buffer that's been initialized by firmware before the kernel boots.

This option was enabled to have display working on the Exynos5250
Snow Chromebook by commit da9d0fbf ("ARM: exynos: defconfig
update") since proper DRM/KMS support did not exist at that time.

But now that the Exynos DRM driver has support for this hardware,
there is no need to have simplefb enabled. In fact, if a user has
a u-boot that injects the simplefb dev node to the FDT before pass
it to the kernel, display won't be properly initialized and only a
blank screen will be shown since there isn't a proper handoff from
the simplefb driver to the Exynos DRM driver.
