[PATCH v2] media: venus: core: Fix some resource leaks in the error path of 'venus_probe()'

[PATCH v2] media: venus: core: Fix some resource leaks in the error path of 'venus_probe()'

[Christophe JAILLET]

If an error occurs after a successful 'of_icc_get()' call, it must be
undone.

Use 'devm_of_icc_get()' instead of 'of_icc_get()' to avoid the leak.
Update the remove function accordingly and axe the now unneeded
'icc_put()' calls.

Fixes: 32f0a6ddc8c9 ("media: venus: Use on-chip interconnect API")

v1->v2: use managed resources instead of expanding the error handling path.
