media: mmp: Bring back registration of the device

Browse Source 
BugLink: https://bugs.launchpad.net/bugs/2114239

commit fbb5298bf1a7b71723cd2bb193642429ceb0fb84 upstream.

In commit 4af65141e3 ("media: marvell: cafe: Register V4L2 device
earlier"), a call to v4l2_device_register() was moved away from
mccic_register() into its caller, marvell/cafe's cafe_pci_probe().
This is not the only caller though -- there's also marvell/mmp.

Add v4l2_device_register() into mmpcam_probe() to unbreak the MMP camera
driver, in a fashion analogous to what's been done to the Cafe driver.
Same for the teardown path.
