media: mali-c55: Initialise dev for tpg/rsz/isp subdevs

The subdevices registered by the Mali-C55 driver do not have their
'struct device *dev' member initialized. This is visibile when looking
at debug message, as in example:

"(NULL device *): collect_streams: sub-device 'mali-c55 tpg' does not
 support streams"

Fix this by initializing the *dev field for each subdevice registered
by the Mali-C55 driver.
