media: ti-vpe: cal: Use ARRAY_SIZE to replace numerical value

Browse Source 
Use ARRAY_SIZE(cal->ctx) to iterate over the cal->ctx array instead of
using the numerical value from the CAL_NUM_CONTEXT macro (or, worse,
hardcoding the value 2). This will allow reworking contexts with less
changes in the code.
