[PATCH 6.1 0915/1191] soc: fsl: qe: check platform_driver_register() in qe_ic_of_init()

6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Linkai Gong <redacted>

[ Upstream commit fbdba2a67fa7c0e7570bcbf9f28b782d6100270d ]

qe_ic_of_init() ignored the return value of platform_driver_register()
and always returned success. Propagate the error to the initcall.
