Subject: [PATCH 3.12 045/144] ARM: DRA7: hwmod: Fix boot crash with DEBUG_LL

3.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Rajendra Nayak <rnayak@...com>

commit 38958c15dc640a9249e4f0cd0dfb0ddc7a23464d upstream.

With commit '7dedd34: ARM: OMAP2+: hwmod: Fix a crash in _setup_reset() with
 DEBUG_LL' we moved from parsing cmdline to identify uart used for earlycon
to using the requsite hwmod CONFIG_DEBUG_OMAPxUARTy FLAGS.

On DRA7 though, we seem to be missing this flag, and atleast on the DRA7 EVM
where we use uart1 for console, boot fails with DEBUG_LL enabled.
