uart: Redefine Kconfig options

Option DRIVERS_UART builds with support for UART hardware.
Option CONSOLE_SERIAL enables the console output for UART.

Those x86 boards that do not have serial port on SuperIO should select
NO_UART_ON_SUPERIO to disable 8250 UART for the default configuration.

Removes:
  CONSOLE_SERIAL_UART
  HAVE_UART_IO_MAPPED
  HAVE_UART_MEMORY_MAPPED

Renames:
  CONSOLE_SERIAL8250     ->  DRIVERS_UART_8250IO
  CONSOLE_SERIAL8250MEM  ->  DRIVERS_UART_8250MEM
