[PATCH AUTOSEL 5.1 28/51] ASoC: Intel: bytcht_es8316: fix kernel oops with platform_name override

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

[ Upstream commit 79136a016add1acb690fe8d96be50dd22a143d26 ]

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.
