serial: 8250_men_mcb: Remove duplicate UAPI:serial_core inclusion

The UAPI serial_core.h is guaranteed to be included by in-kernel
one (with the same name). Individual drivers do not need to include
it explicitly. Remove it from the driver.

Note, it's a single driver in the entire kernel that does this.
