i.MX: Move UART definitions into a separate file
Move UART definitions into a separate file to avoid redefinition in <mach/debug_ll.h> and magical constants in low level UART initialization code. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
