Subject: [PATCH v3 10/11] cxl/pmem: Remove match_nvdimm_bridge()

From: Zijun Hu <quic_zijuhu@...cinc.com>

match_nvdimm_bridge(), as matching function of device_find_child(), is to
match a device with device type @cxl_nvdimm_bridge_type, and is unnecessary

Remove it and use API device_match_type() plus the device type instead.
