Series x86: serial: Use NS16550_DYNAMIC in Slim Bootloader | expand

Commit Message

Park, Aiden Dec. 18, 2019, 5:56 a.m. UTC 
Now, Slim Bootloader uses NS16550_DYNAMIC to support serial port
configuration at runtime, so no more code change is required.
Therefore, remove unnecessary steps and fix minor typo.
