This patch adds a unified s3c24x0 cpu header file that selects the header
file for the specific s3c24x0 cpu from the SOC and CPU configs defined in
board config file. This removes the current chain of s3c24-type #ifdef's
from the s3c24x0 code.

This patch moves the s3c24x0 header files from include/ to
include/asm-arm/arch-s3c24x0/.
checkpatch.pl showed 2 errors and 3 warnings. The 2 errors were both due
to a non-UTF8 character in David M?ller's name:
ERROR: Invalid UTF-8, patch and commit message should be encoded in UTF-8
#489: FILE: include/asm-arm/arch-s3c24x0/s3c2410.h:3:
+ * David M?ller ELSOFT AG Switzerland. d.mueller@elsoft.ch
As David's name correctly contains a non-UTF8 character I haven't fixed
these errors.
The 3 warnings were all because of the use of 'volatile' in s3c24x0.h:
WARNING: Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt
#673: FILE: include/asm-arm/arch-s3c24x0/s3c24x0.h:35:
+typedef volatile u8 S3C24X0_REG8;
+typedef volatile u16 S3C24X0_REG16;
+typedef volatile u32 S3C24X0_REG32;
I'll fix these errors in another patch.
Tested by running MAKEALL for ARM8 targets and ensuring there were no new
errors or warnings.

This patch re-formats the code in cpu/arm920t and cpu/arm920t/23c24x0 in
preparation for changes to add support for the Embest SBC2440-II Board.
The changes are as follows:
- re-indent the code using Lindent
- make sure register layouts are defined using a C struct
- replace the upper-case typedef'ed C struct names with lower case
non-typedef'ed ones
- make sure registers are accessed using the proper accessor functions
- run checkpatch.pl and fix any error reports
It assumes the following patch has been applied first:
- [U-Boot][PATCH-ARM] CONFIG_SYS_HZ fix for ARM902T S3C24X0 Boards, 05/09/2009
Tested on an Embest SBC2440-II Board with local u-boot patches as I don't have
any s3c2400 or s3c2410 boards but need this patch applying before I can submit
patches for the SBC2440-II Board. Also, ran MAKEALL for all ARM9 targets and no
new warnings or errors were found.

actually the timer init use the interrupt_init as init callback
which make the interrupt and timer implementation difficult to follow
so now rename it as int timer_init(void) and use interrupt_init for interrupt
btw also remane the corresponding file to the functionnality implemented
as ixp arch implement two timer - one based on interrupt - so all the timer
related code is moved to timer.c

This patch adds a IRQ demultiplexer callback to the arm920 cpu core code,
plus a stub implementation of it for the S3C2410.
The purpose is to allow arm920t implementations such as the s3c24x0 to
implement interrupt handlers in u-boot without having to touch core
arm920t code.

- Use i.MX watchdog timer for reset_cpu()
- Move reset_cpu() out of cpu/arm920t/start.S into the SoC specific
subdirectories cpu/arm920t/imx/ and cpu/arm920t/s3c24x0/
(now in interupts.c)
- Introducing the concept of SoCs "./cpu/$(CPU)/$(SOC)"
- creating subdirs for SoCs ./cpu/arm920t/imx and ./cpu/arm920t/s3c24x0
- moving SoC specific code out of cpu/arm920t/ into cpu/arm920t/$(SOC)/
- moving drivers/s3c24x0_i2c.c and drivers/serial_imx.c out of drivers/
into cpu/arm920t/$(SOC)/
