libpayload: refactor fetching cbmem pointers
There's a recurring pattern of reading cbtable entries that point into
cbmem entries. Move that pattern into its own function.
Coccinelle patch used for this:
@@
identifier T, T2;
expression TARGET;
@@
-struct cb_cbmem_tab *const T2 = (struct cb_cbmem_tab *)T;
-TARGET = phys_to_virt(T2->cbmem_tab);
+TARGET = get_cbmem_ptr(T);
