[PATCH 0/2] Fix omap serial early crash during hwmod _setup()

This series should fix the issue with the early serial crash seen
during hwmod _setup() as reported by [1]

The issue was reported on a am33xx device and was not seen on omap4
or omap5 devices as the hwmod data for both omap4 and omap5 had
statically defined HWMOD_INIT_NO_IDLE and HWMOD_INIT_NO_RESET for
uart3 which happens to be the debug console used on omap4 panda and
omap5 uevm boards.

The series reverts the patch which stubbed out omap_serial_early_init()
for DT boot and gets rid of the static flags in omap4 and omap5 hwmod

This series along with the patch posted by Felipe [2] should fix the
issue reported by [1] completely and boot to prompt on a am33xx device
with LL_DEBUG enabled.

I have boot tested this series (along with [2]) on a omap4 panda es and
a am335x boneblack.
