cmd: adtimg: Refactor usage style

Trying to extend 'adtimg' functionality [1], we've been severely hit
by a major limitation in the command's usage scheme. Specifically, the
command's user interface appears to be too centric to getting the
DTB/DTBO entry [3] based on the index of the desired DT in the image,
which makes it really difficult retrieving the DT entry based on
alternative criteria (e.g. filtering by id/rev fields), the
latter being demanded by real life customer use-cases [1].

This went to the point of receiving below feedback from Sam [2]:

 -- snip --
 As for 'dtimg' command: after giving it some thought, I think not much
 people using it yet. So in this particular case I don't have some
 strong preference, and if you think the 'dtimg' interface is ugly, and
 it overcomes "don't break interfaces" rule, maybe now is a good time
 to rework it (before it gets widely used).
 -- snip --

Given the above, rework the usage pattern from [4] to [5], in order to
allow an intuitive enablement of "by id|rev" DT search [6].

mpc83xx_clk: always treat MPC83XX_CLK_PCI as invalid

The current mpc83xx_clk driver is broken for any board for which
mpc83xx_has_pci() is true, i.e. anything not MPC8308:

When is_clk_valid() reports that MPC83XX_CLK_PCI is valid,
init_all_clks() proceeds to call init_single_clk(), but that doesn't
know about either MPC83XX_CLK_PCI or has any handling of the
TYPE_SCCR_ONOFF mode correctly returned by retrieve_mode(). Hence
init_single_clk() ends up returning -EINVAL, and the whole board hangs
in serial_init().

The quickest fix is to simply pretend that clock is invalid for
all, since nobody can have been relying on it. Adding proper support
seems to be a bit more involved than just handling TYPE_SCCR_ONOFF:

- The power-on-reset value of SCCR[PCICM] is 0, so
  mpc83xx_clk_enable() would probably need to be tought to enable the
  clock.

- The frequency of PCI_SYNC_OUT is either SYS_CLK_IN or SYS_CLK_IN/2
  depending on the CFG_CLKIN_DIV configuration input, but that can't
  be read from software, so to properly fill out
  ->speed[MPC83XX_CLK_PCI] I think one would need guidance from
  Kconfig or dtb.

aspeed: ast2500: Read clock ofdata in the correct method

At present the clock driver reads its ofdata in the probe() method. This
is not correct although it is often harmless.

However in this case it causes a problem, something like this:

- ast_get_scu() is called (from somewhere) to get the SCI address
- this probes the clock
   - first sets up ofdata (which does nothing at present)
   - DM marks clock device as active
   - DM calls pinctrl
      - pinctrl probes and calls ast_get_scu() in ast2500_pinctrl_probe()
      - ast_get_scu() probes the clock, but sees it already marked as
           probed
      - ast_get_scu() accesses the clock's private data, with scu as NULL
   - DM calls clock probe function ast2500_clk_probe() which reads scu

By putting the read of scu into the correct method, scu is read as part of
ofdata setup, and everything is OK.

Note: This problem did not matter until now since DM always probed all
parents before reading a child's ofdata. The fact that pinctrl is a child
of clock seems to trigger this strange bug.
