[MIPS] Alchemy: move UART platform code to its proper place
Move the code registering the Alchemy UART platform devices from drivers/serial/ to its proper place, into the Alchemy platform code. Fix the related Kconfig entry, while at it... Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
