Treewide: remove address of the Free Software Foundation ...

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

Samsung/serial: make the clock source configureable ...

Instead of taking the value from somewhere, use the selected architecture to
select one. This ensures the selected clock source corresponds to the values
setup in the clocks-*.c from the mach directory.

Samsung/serial: unify UCON register settings ...

This should work on S3C24XX and S3C64XX SoCs.

Tested at runtime on a Mini2440 and Mini6410.

Samsung/serial: move the decision about an improved UART into Kconfig ...

More or less just cosmetic (removing ifdefs!).

Samsung/serial: there is no need to ifdef the slot table ...

The '__maybe_unused' attribute prevents the compiler from warning about an
unused variable and the 'static' will remove it entirely if it's not used.
This patch is only cosmetic.

Support most Samsung SoCs in S3C serial driver ...

Ok, I assume this should go into separate series. It fits both S5PV210 and S3C6410.

This adds support for S3C and S5P architectures (all of my knowledge) to the
serial driver. Since the only difference between them is in clock handling,
this is moved to an arch-dependent separate function.

Most modern architectures should define S3C_UART_HAS_UBRDIVSLOT and S3C_UART_HAS_UINTM.

This adds support for most
