Subject: [PATCHv3 01/10] tty: serial: omap: add UPF_BOOT_AUTOCONF flag for DT init

The UPF_BOOT_AUTOCONF flag is needed for proper
flow control support.

Hi,

This patch can be queued independently - there is no compile time dependency
regarding nokia-bluetooth. Also 8250_omap.c can be used with nokia-bluetooth
(I use this driver nowadays), which does flow control right already.
