ARM: DRA7: hwmod: Fix boot crash with DEBUG_LL enabled on UART3
commit 1c7e36bfc3e2fb2df5e2d1989a4b6fb9055a0f9b 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 UART3 hwmod doesn't have this flag enabled, and atleast on
BeagleBoard-X15, where we use UART3 for console, boot fails with
DEBUG_LL enabled. Enable DEBUG_OMAP4UART3_FLAGS for UART3 hwmod.
For using DEBUG_LL, enable CONFIG_DEBUG_OMAP4UART3 in menuconfig.
Fixes: 90020c7b2c5e ("ARM: OMAP: DRA7: hwmod: Create initial DRA7XX SoC data")
