Subject: [PATCH] Revert "serial-uartlite: Constify uartlite_be/uartlite_le"

This reverts commit 2905697a82eaf20606ced164d853b52d1b94aaa8.

The commit introduced two build warnings:
drivers/tty/serial/uartlite.c: In function ‘ulite_request_port’:
drivers/tty/serial/uartlite.c:348:21: warning: assignment discards
			‘const’ qualifier from pointer target type
  port->private_data = &uartlite_be;
                     ^
drivers/tty/serial/uartlite.c:354:22: warning: assignment discards
			‘const’ qualifier from pointer target type
   port->private_data = &uartlite_le;
                      ^
