media: venus: core: Fix some resource leaks in the error path of 'venus_probe()'
[ Upstream commit 5a465c5391a856a0c1e9554964d660676c35d1b2 ]
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.
