i2c: designware: use dev_err_probe() when probing platform device 

Add calls to dev_err_probe() on error paths that can return
-EPROBE_DEFER when probing platform device. Namely when requesting the
reset controller, when probing for lock support and when requesting the
clocks.

PCI device probing already use dev_err_probe().
