ARM: OMAP2+: Fix OF node reference leaks in omap_hwmod

The OF helpers that return device nodes acquire references that must be
released by the caller.

_init() leaks the "ocp" bus node returned by of_find_node_by_name() on
all paths after lookup, and also leaks the child returned by
of_get_next_child() when parsing module flags. Route the post-lookup
returns through a common cleanup path and release the child after use.

omap_hwmod_setup_earlycon_flags() leaks the /chosen node and the UART
node resolved from stdout-path. Track them separately and drop both
references after use.
