The mtk clock framework in u-boot uses array index for searching clock
parent (kernel uses strings for search), so we need to specify a special
clock with ID=0 for CLK_XTAL in u-boot.
In the mt7622/mt7629 clock tree, the clocks with ID=0 never call
mtk_topckgen_get_mux_rate, adn return xtal clock directly. This what we
expected.
However for newer chips, they may have some clocks with ID=0 not
representing the xtal clock and still needs mtk_topckgen_get_mux_rate be
called. Current logic will make entire clock driver not working.
This patch adds a flag to indicate that whether a clock driver needs clocks
with ID=0 to call mtk_topckgen_get_mux_rate.

In the spirit of using the same base name for all of these related macros,
rename this to have the operation at the end. This is not widely used so
the impact is fairly small.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

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.

The control block is shared with ethsys and accordingly rename the
related defines.

This patch adds clock modules for MediaTek SoCs:
- Shared part: a common driver which contains the general operations
for plls, muxes, dividers and gates so that we can reuse it in future.
- Specific SoC part: the group of structures used to hold the hardware
configuration for each SoC.
We take MT7629 as an example to demonstrate how to implement driver if
any other MediaTek chips would like to use it.
