The arch/arm/mach-exynos4 directory (CONFIG_ARCH_EXYNOS4) has
made for plaforms based on EXYNOS4 SoCs. But since upcoming
Samsung's SoCs such as EXYNOS5 (ARM Cortex A15) can reuse most
codes in current mach-exynos4, one mach-exynos directory will
be used for them.
This patch changes to CONFIG_ARCH_EXYNOS (arch/arm/mach-exynos)
but keeps original CONFIG_ARCH_EXYNOS4 in mach-exynos/Kconfig to
avoid changing in driver side.

The IS_SAMSUNG_CPU() macro works by comparing the CPU ID mask exactly with
the CPU ID. This was failing for S3C64xx SoCs as in order to support
identification of the exact device the mask covers both variants of the
chip, meaning that the test would always fail on S3C6410 devices. This in
turn caused the core GPIO subsystem to fail to identify the CPU and not
support any GPIOs, crippling the system.
As a minimally invasive fix change the test for the class to be done by
checking each implementation and oring them together.

Previously the fclk rate was calculated by dividing the pll through
the divider value of the armdiv. With a real armdiv clk in place it's
possible to simply read its value, which does essentially the same.
This change makes the whole fdiv_fn function pointers supplied to
s3c2443_common_init_clocks and s3c2443_common_setup_clocks
obsolete, so remove it too.

This patch adds common DMA operations which are used for Samsung DMA
drivers. Currently there are two types of DMA driver for Samsung SoCs.
The one is S3C-DMA for S3C SoCs and the other is PL330-DMA for S5P SoCs.
This patch provides funcion pointers for common DMA operations to DMA
client driver like SPI and Audio. It makes DMA client drivers support
multi-platform.
In addition, this common DMA operations implement the shared actions
that are needed for DMA client driver. For example shared actions are
filter() function for dma_request_channel() and parameter passing for
device_prep_slave_sg().
