phy: broadcom: ns-usb3: Fix Wvoid-pointer-to-enum-cast warning (again)

"family" is an enum, thus cast of pointer on 64-bit compile test with
clang W=1 causes:

  phy-bcm-ns-usb3.c:206:17: error: cast to smaller integer type 'enum bcm_ns_family' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]

This was already fixed in commit bd6e74a ("phy: broadcom: ns-usb3:
fix Wvoid-pointer-to-enum-cast warning") but then got bad in commit
21bf6fc ("phy: Use device_get_match_data()").

Note that after various discussions the preferred cast is via "unsigned
long", not "uintptr_t".

Fixes: 21bf6fc ("phy: Use device_get_match_data()")
