[PATCH v9 12/17] media: rkvdec: Enable all clocks without naming them

[Detlev Casanova <detlev.casanova@collabora.com>]

For other variants, the clock names and number will differ.

There is no need to keep track of the clock names in the driver so drop
them to avoid having a list for each variant.
