The TCU clock gate on X1000 wasn't requested by the driver and could
be gated automatically later on in boot, which prevents timers from
running and breaks PWM.
Add a workaround to support old device trees that don't specify the
"tcu" clock gate. In this case the kernel will print a warning and
attempt to continue without the clock, which is wrong, but it could
work if "clk_ignore_unused" is in the kernel arguments.

This device id table is passed to of_match_node() later on in probe, but
on CONFIG_OF=n builds of_match_node() doesn't do anything with the
arguments. Lets just mark the table unused so that the compiler doesn't
complain about this.

There are a few manually-calculated variable-length struct allocations
left, this converts them to use struct_size. Found with the following
git grep command
git grep -A1 'kzalloc.*sizeof[^_].*+'
