[PATCH 1/2] serial: ce4100: fix build after serial_in/out() changes

["Jiri Slaby (SUSE)" <jirislaby@kernel.org>]

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.

Signed-off-by: Jiri Slaby (SUSE) <jirislaby@kernel.org>
Fixes: fc9ceb501e38 ("serial: 8250: sanitize uart_port::serial_{in,out}() types")
