[PATCH 5.1 34/96] ASoC: Intel: cht_bsw_rt5672: fix kernel oops with platform_name override

[ Upstream commit 9bbc799318a34061703f2a980e2b6df7fc6760f0 ]

The platform override code uses devm_ functions to allocate memory for
the new name but the card device is not initialized. Fix by moving the
init earlier.
