Setting up the clocks does not work when the stack is in SDRAM.
Moving the stack to SRAM allows us to do the lowlevel clock setup
later.

The X-loader startup relocates to SRAM anyway, so there
is no need to be runnable from flash for the clock code.
This config is disabled in all defconfigs anyway, so remove
it.

The base address passed for device "omap-hsmmc" was
incorrectly passed as OMAP_I2C1_BASE and the base
address for device "i2c-omap" was hardcoded to
0x4809C000 which, in fact, refers to OMAP_MMC1_BASE.
Similarly, in call to add_usb_ehci_device(), addition
is not required if right base address is used.
In fact, 0x48064700 (used as base in the addition)
falls in the OHCI Address space.

After separation and after all S3C macros are now present, change the driver
to be more generic for future additions.
The timer registers in the S3C24XX family are only 16 bit wide. But these
registers can be read and written in a 32 bit manner. This is important to share
code with more recent CPUs which comes with 32 bit registers.

There are major differences in the clock tree of the S3C24xx family and the

avoid an ifdef hell. But also use generic function names to be able to
