The initial import from OpenBSD contained chip revision printf() calls
commented out, as OpenBSD's bare printf() style does not translate to
FreeBSD's device_printf() idiom. The result is that users cannot
distinguish RTL8125 from RTL8125B, RTL8125D_1, RTL8125D_2 etc. via
dmesg alone, even though all variants show as '<RTL8125>' from the PCI
probe string.
Add proper device_printf() calls including the raw hwrev value,
consistent with how re(4) reports chip revisions.
