In function dm814x_adpll_early_init, variable np takes the value
returned by of_find_node_by_name, which gets a node but does not put it.
If np is not put before return, it may cause a memory leak. Hence put np
before return.
Issue found with Coccinelle.

Add data for dm814 clkctrl clocks, and register it within the clkctrl
driver.

Most of the clock aliases are no longer needed, only leave the ones
required by OMAP timer code in place.

drivers/clk/ti/clk-814x.c:34:12: warning: symbol 'dm814x_adpll_early_init' was not declared. Should it be static?

drivers/clk/ti/adpll.c:465 ti_adpll_recalc_rate() warn: should '__readw(d->regs + 20) << 18' be a 64 bit type?
drivers/clk/ti/adpll.c:945 ti_adpll_probe() error: we previously assumed 'd->clocks' could be null (see line 921)
The last one looks like a real bug because we don't return an
error on allocation failure.

On dm814x we have 13 ADPLLs with 3 to 4 outputs on each. The
ADPLLs have several dividers and muxes controlled by a shared
control register for each PLL.
Note that for the clocks to work as device drivers for booting on
dm814x, this patch depends on "ARM: OMAP2+: Change core_initcall
levels to postcore_initcall" that has already been merged.
Also note that this patch does not implement clk_set_rate for the
PLL, that will be posted later on when available.

The timer clock aliases are needed early on dm814x. Let's also
add the aliases for the interconnects and MMC.

Let's add a minimal clocks for dm814x to get it booted. This is
mostly a placeholder and relies on the PLLs being on from the
bootloader.
Note that the divider clocks work the same way as on dm816x and
am335x.
