media: vimc: expand the names of vimc entity types



When introducing the lens controller, it became apparent that the vimc
entity type names were hard to understand, e.g. vimc_len_type refers to the
lens. The names of the vimc entity types have been expanded to make the
code easier to understand. There is no functional change intended.
