media: ti-vpe: cal: Use a loop to create CAMERARX and context instances

Replace a manually unrolled loop with an explicit for loop to increase
readability when creating the CAMERARX and context instances. The
explicit NULL initialization of cal->phy[] and cal->ctx[] is removed, as
the cal structure is zeroed when allocated.
