[PATCH v2 6/9] media: ov2740: Check hwcfg after allocating the ov2740 struct

[Hans de Goede <hdegoede@redhat.com>]

Alloc ov2740_data and set up the drvdata pointer before calling
ov2740_check_hwcfg().

This is a preparation patch to allow ov2740_check_hwcfg()
to store some of the parsed data in the ov2740 struct.
