This patch adds chained IRQ enter/exit functions to uart
interrupt handler in order to function correctly on primary
controllers with different methods of flow control.

Reorder
irq_set_chip()
irq_set_chip_data()
irq_set_handler()
to
irq_set_chip()
irq_set_handler()
irq_set_chip_data()
so the next patch can combine irq_set_chip() and irq_set_handler() to
irq_set_chip_and_handler().
Automated conversion with coccinelle.

When GENERIC_HARDIRQS_NO_DEPRECATED is enabled, a number of struct
irq_desc members stop being directly accessible, and need to be
accessed via the irq_data struct instead -- this patch fixes up the
plat-samsung sites that still access those members directly.

Convert to the new irq_ versions of the IRQ operations. As well as
the textual substituion of irq_data for the raw IRQ number we also
convert the register base lookup to in s3c_irq_uart_base() to pick
the irq_data up directly.

Move the handling for the UART interrupts out of the s3c64xx specific
code and into plat-samsung so that it can be used by all implementations
that need it.
