pinctrl: qcom: tlmm-test: Add const to reg_names 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 "const char **", but the converted allocation type
would be "char **", which is the same type without the const qualifier.
As there is no general way to safely add 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:
drivers/pinctrl/qcom/tlmm-test.o
