Correct capable baseband in dmesg for RTL8188E chips

[Ricardo Mestre]

Hi tech@

During stsp@'s effort to merge rtwn(4) and urtwn(4), more specifically since
r1.6 of /cvs/src/sys/dev/ic/rtwn.c, my urtwn(4) device started showing in dmesg
with a capable baseband of 0T0R (only noticed it today!):

urtwn0: MAC/BB RTL8188EU, RF 6052 0T0R, address xx:xx:xx:xx:xx:xx

Since according to urtwn(4)'s manpage both RTL8188C and RTL8188E chips have a
1T1R capable baseband please find below a patch to correct this.

OK?
