media: platform: add missing put_device() call in mtk_jpeg_probe() and mtk_jpeg_remove()

Browse Source 
[ Upstream commit 0d72f48999 ]

if mtk_jpeg_clk_init() succeed, mtk_jpeg_probe() and mtk_jpeg_remove()
doesn't have a corresponding put_device(). Thus add a new helper
mtk_jpeg_clk_release() to fix it.
