The clock and reset drivers use the exact same platform data. Simplify
them by sharing the object. This is safe because the parent device
(the clock device) always gets its driver model callbacks run first.

All of the driver private data should really be platform data since it
is determined statically (selected by the compatible string or extracted
from the devicetree). Move everything to platform data, so it can be
provided when binding the driver. This is useful for SPL, or for
instantiating the driver as part of an MFD.

Now that all of the variants use the same bind/probe functions and ops,
there is no need to have a separate driver for each variant. Since most
SoCs contain two variants (the main CCU and PRCM CCU), this saves a bit

Because the gate arrays are not given explicit sizes, the arrays are
only as large as the highest-numbered gate described in the driver.
However, only a subset of the CCU clocks are needed by U-Boot. So there
are valid clock specifiers with indexes greater than the size of the
arrays. Referencing any of these clocks causes out-of-bounds access.
Fix this by checking the identifier against the size of the array.

The reset array size is currently used for bounds checking in the reset
driver. The same bounds check should really be done in the clock driver.
Currently, the array size is provided to the reset driver separately
from the CCU descriptor, which is a bit strange. Let's do this the usual
way, with the array sizes next to the arrays themselves.

Some devices enumerate various clocks in their DT, and many drivers
just blanketly try to enable all of them. This creates problems
since we only model a few gate clocks, and the clock driver outputs
a warning when a clock is not described:
=========
sunxi_set_gate: (CLK#3) unhandled
=========
Some clocks don't have an enable bit, or are already enabled in a
different way, so we might want to just ignore them.
Add a CCU_CLK_F_DUMMY_GATE flag that indicates that case, and define
a GATE_DUMMY macro that can be used in the clock description array.
Define a few clocks, used by some pinctrl devices, that way to suppress
the runtime warnings.

The introduction of the DM pinctrl driver made its probe function enable
all clocks enumerated in the DT. This includes the "CLK_BUS_PIO" (and
variations) gate clock. Also CLK_PLL_PERIPH0 is used by the R_CCU device.
So far we didn't describe those clocks in our clock driver.
As we enable them already in the SPL, the devices happen to work, but
the clock driver still complains about not finding those clocks:
=========
sunxi_set_gate: (CLK#58) unhandled
=========
Add the one-liners that are needed to announce the gate bit for those
clocks, to silence that message on the console.

Add the clock driver for the rk3066 platform.
Derived from the rk3288 and rk3188 driver it
supports only a bare minimum to bring up the system
to reduce the TPL size for:
SDRAM clock configuration.
The boot devices NAND, EMMC, SDMMC, SPI.
A UART for the debug messages (fixed) at 115200n8.
A SARADC for the recovery button.
A TIMER for the delays (fixed).
There's support for two possible frequencies,
the safe 600MHz which will work with default pmic settings and
will be set to get away from the 24MHz default and
the maximum of 1.416Ghz, which boards can set if they
were able to get pmic support for it.
After the clock tree is set during the TPL probe
there's no parent update support.
In OF_REAL mode the drivers ns16550.c and dw-apb-timer.c
obtain the (fixed) clk_get_rate from the clock driver
instead of platdata.
The rk3066 cru node has a number of assigned-clocks properties
that call the .set_rate() function. Add them to the list so that
they return a 0 instead of -ENOENT.
