The S3C64XX series has a new TCFG divider setting to allow the clock
directly through, which means that we need to update the pwm-clock
code to cope with this.
Add <mach/pwm-clock.h> containing the specific code to deal with the
TCFG divider settings and provide any other per-arch data that the
pwm-clock driver needs to function.

The function s3c64xx_init_io was missing from <plat/cpu.h>
and was masked by the SMDK6410 having an local definition.
Fix by removing the SMDK6410 variant and adding it to the
relevant <plat/cpu.h> file.

The clk_fout_epll clock wasn't registered as part of the initial clock

Add the necessary code to support IRQ_EINT(x) on
the S3C64XX series of CPUs.
Note, since there is no GPIO configuration support
in the kernel, the irq set_type method does not
configure the relevant pin to interrupt.

The pwm-scaler0 and pwm-scaler1 clocks have their
.id field set to -1 as they are not referenced to
any specific device. However, parts of the pwm-clock
code used the .id field to identify which scaler
clock was being used.
Fix the problem by comparing against the pointer to
the clock to identify the scalers.

All the s3c24xx gpiolib chips share the same get/set
calls and all but one bank shares the same calls for
.direction_input and .direction_output methods.

to register the chips that fills in any blank calls
with the default values to avoid having to fill them

Add a simple check when registering a clock on whether
the clock has already been added to the list.
Any attempt to re-register a clock will cause the
clock list to be come looped and thus produces silent
failures when looking up clocks.
