Commit 32726d2d5502 ("ARM: SAMSUNG: Remove legacy clock code") removed
the Kconfig symbol SAMSUNG_CLOCK. Remove the last checks for its macro,
and the dead code they hide, too.

This trivial fix has been discussed for some time now in the thread
starting at http://lkml.kernel.org/r/1405502840.4408.2.camel@x220 It
seems it's time to submit it.
Build tested on top of next-20141003, on x86_64 (!), with these horrific
commands:
make EXTRA_CFLAGS=-DCONFIG_SERIAL_SAMSUNG_UARTS=3 drivers/tty/serial/samsung.o
make EXTRA_CFLAGS=-DCONFIG_SERIAL_SAMSUNG_UARTS=4 drivers/tty/serial/samsung.o
Please note that
make EXTRA_CFLAGS=-DCONFIG_SERIAL_SAMSUNG_UARTS=0 drivers/tty/serial/samsung.o
doesn't build. Perhaps some "range" should be added to config
SERIAL_SAMSUNG_UARTS. And I also wonder whether SERIAL_SAMSUNG_UARTS
should be a dependency (somehow) of config SERIAL_SAMSUNG. I have not
looked into those questions.
