[PATCH] arm: mach-k3: am642: Fix reset for workaround errata ID i2331

[Andrew Davis <afd@ti.com>]

To workaround an issue in AM642 we reset the SoC in early boot. For that
we first probed the sysreset driver by calling uclass_get_device(). The
ti-sci sysreset driver is now probed during the ti-sci firmware probe.
Update this call to probe the firmware driver which will then probe
the sysreset driver allowing do_reset() to again function as expected.
