OMAP4: ST: Disabling UART if ldisc not installed.
In cases when there is no line discipline to be installed UART chip must be
disabled.
Rationale: if ldisc is not installed so it can't be uninstalled.
Thus UART chip still enabled and we have wakelock for it
(see plat_uart_enable() function in both blaze and 44xx-tablet board files).
In that case we can't go in suspend mode.
Motivation: when using busybox ramdisk (e.g. for testing kernel w/o AFS) we
have no ldisc that causes impossibility to go to suspend mode.
