clk: bcm281xx: initialize CCU structures statically

We know up front how many CCU's we'll support, so there's no need to
allocate their data structures dynamically.  Define a macro
KONA_CCU_COMMON() to simplify the initialization of many of the
fields in a ccu_data structure.  Pass the address of a statically
defined CCU structure to kona_dt_ccu_setup() rather than having that
function allocate one.

We also know at build time how many clocks a given CCU will provide,
though the number of of them for each CCU is different.  Record the
number of clocks we need in the CCU's clk_onecell_data struct
(which is used when we register the CCU with the common clock code
as a clock provider).  Rename that struct field "clk_data" (because
"data" alone gets a little confusing).

Use the known clock count to move the allocation of each CCU's
clocks array into ccu_clks_setup() rather than having each CCU's
setup callback function do it.

(The real motivation behind all of this is that we'll be doing some
static initialization of some additional CCU-specific data soon.)
