Initial architecture support for the S3C24A0 ARCH_S3C24A0.

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

with the default values to avoid having to fill them
in the structure initialisers.

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
