This enables CONFIG_EFI for multi_v7_defconfig, which adds support for
booting via EFI, and for the EFI framebuffer as builtin options. It
also enables the EFI rtc, the EFI variable pseudo-filesystem and the
EFI capsule loader as modules.

The driver is for a trackpad device so is not needed for booting and
makes more sense to have it as module to reduce the kernel image size.
It was probably enabled as built-in because module autoload was not
working when the I2C device was registered by OF but this got fixed
in commit b7d21058b4 ("Input: atmel_mxt_ts - add maxtouch to I2C
table for module autoload") so it's safe to enable as a module now.

This pull request contains defconfig changes for Broadcom ARM-based SoCs:
- Florian enables support for the BCM63xx DSL SoCs basic peripherals, enables
the networking subsystems for Set Top Box SoCs, enables the PWM, watchdog and
the AHCI controller and SATA PHY drivers
- Florian removes the bcm_defconfig file which is no longer useful and updates
multi_v7_defconfig to include the Kona watchdog to provide proper reboot for the
Broadcom Kona platforms
Please note that Tejun Heo has queued a patch which renames AHCI_BRCMSTB into
AHCI_BRCM, to avoid two patches in a row, we just enable AHCI_BRCM to be future
proof

The Exynos SoC provides a Security SubSystem block for accelerating some
cryptographic operations. Enable the driver for it - s5p-secss to
utilize the hardware acceleration.

The samsung-keypad driver is implicitly selected by ARCH_EXYNOS4 (why?),
but this fails if CONFIG_INPUT is a loadable module:
drivers/input/built-in.o: In function `samsung_keypad_remove':

drivers/input/built-in.o: In function `samsung_keypad_irq':

drivers/input/built-in.o:(.debug_addr+0x34): undefined reference to `input_set_capability'
This removes the 'select' as suggested by Krzysztof Kozlowski and
instead enables the driver from the defconfig files.
The problem does not happen on mainline kernels, as we don't normally
build built-in input drivers when CONFIG_INPUT=m, but I am experimenting
with a patch to change this, and the samsung keypad driver showed up
as one example that was silently broken before.
