pmdomain: ti: Add a null pointer check to the omap_prm_domain_init

Browse Source 
commit 5d7f58ee08434a33340f75ac7ac5071eea9673b3 upstream.

devm_kasprintf() returns a pointer to dynamically allocated memory
which can be NULL upon failure. Ensure the allocation was successful
by checking the pointer validity.
