ARM: SAMSUNG: Add soc_is_s3c6400/s3c6410 macros

This patch adds soc_is_s3c6400() and soc_is_s3c6410() macros that allow
to distinguish between specific SoCs from s3c64xx series that is needed
to handle differences between them.

This patch modifies s3c64xx DMA driver to prepare and unprepare clocks
in addition to enableind and disabling, since it is required by common
clock framework.

of: irq: Pass trigger type in IRQ resource flags

Some drivers might rely on availability of trigger flags in IRQ
resource, for example to configure the hardware for particular interrupt
type. However current code creating IRQ resources from data in device
tree does not configure trigger flags in resulting resources.

This patch tries to solve the problem, based on the fact that
irq_of_parse_and_map() configures the trigger based on DT interrupt
specifier and IRQD_TRIGGER_* flags are consistent with IORESOURCE_IRQ_*,
and we can get correct trigger flags by calling irqd_get_trigger_type()
after mapping the interrupt.
