mtk_clk_find_parent_rate is calling clk_get_rate to know the rate
of a parent clock. clk_get_rate returns a ulong, while
mtk_clk_find_parent_rate returns an int. This implicit cast creates
an issue for clock rates big enough to need the full 32 bits to
store its data. When that happen the clk rate will become incorrect
because of the implicit cast between ulong -> int -> ulong.
This commit change the return type of mtk_clk_find_parent_rate to
ulong.

Add slack to the clock frequency parameters passed to firmware within
clk_set_rate. min-freq is changed to 0 and max-rate is changed to
ULONG_MAX. This fixes certain issues with pll clock rounding when the
firmware is not able to set the frequency exactly to the target, the
current implementation fails if the available frequency is even 1Hz off
the target. With the change, the firmware still tries its best to set
the frequency as close as possible to the target.

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.

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.
