gpio: it87: Remove const from labels_table allocation type

Browse Source 
In preparation for converting the kmalloc family of allocators to the
type-aware kmalloc_obj family, we need to make sure that the returned
type from the allocation matches the type of the variable being
assigned. (The kmalloc family returns "void *", which can be implicitly
cast to any pointer type.)

The assigned type is "char **", but the converted allocation type would
be "const char **", which is const qualified. As there is no general way
to remove const qualifiers, take the size from the assignment target
instead. No change in allocation size results.

Build tested ARCH=x86_64 allmodconfig with GCC 16.2.0:
