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.
