fpga: bridge: Use standard dev_release for class driver 

mainline inclusion
from mainline-v5.17-rc1
commit 0d70af3c
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/IA7YMH

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0d70af3c2530a70f1b2c197feaa63fbd3548ce34



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

The FPGA bridge class driver data structure is being treated as a
managed resource instead of using the standard dev_release call-back
function to release the class data structure. This change removes
the managed resource code and combines the create() and register()
functions into a single register() function.
