serial: ce4100: fix build after serial_in/out() changes

This x86_32 driver remain unnoticed, so after the commit below, the
compilation now fails with:
  arch/x86/platform/ce4100/ce4100.c:107:16: error: incompatible function pointer types assigning to '...' from '...'

To fix the error, convert also ce4100 to the new
uart_port::serial_{in,out}() types.
