This commit enables the following configs:
- CONFIG_USE_ARCH_MEMCPY
- CONFIG_USE_ARCH_MEMSET
This increases the performance of memcpy/memset
and also reduces the boot time.
This was tested on Trats2.
A quick test with trace. Boot time from start to main_loop() entry:
- ~1527ms - before this change (arch memset enabled for .bss clear)
- ~1384ms - after this change

I was running into this limit with a not overly long PXE append line.
Since the PXE code wants to print the resulting command line increase
CONFIG_SYS_PBSIZE too.

...and remove explicit setting of things which this implies. This is done for
all exynos platforms (4 & 5) so it is added to exynos-common.h
I'm mainly interested in CONFIG_CMD_BOOTZ and CONFIG_SUPPORT_RAW_INITRD
I have build tested on all exynos platforms (MAKEALL -s exynos), but only boot
tested on arndale.

This config is required by Odroid, and could be also useful for the other
boards.

Use driver model for exynos5 board SPI flash.

Move the exynos SPI driver over to driver model. This removes quite a bit
of boilerplate from the driver, although it adds some for driver model.
A few device tree additions are needed to make the SPI flash available.

Convert the exynos GPIO driver to driver model. This implements the generic
GPIO interface but not the extra Exynos-specific functions.

Most of the arndale features are common with other exynos5250 boards. To
permit easier addition of driver model support, use the common file.

Since exynos4 and exyno5 share many settings, we should move these into
a common file to avoid duplication.
In effect the changes are that all exynos boards now have EXT4 and FAT
write support. This affects exynos5250 and exynos5420 which previously
did not. This also disables the ext2 commands which are equivalent to
ext4 anyway.
