mailmap: map Uwe's BayLibre addresses to a single one

When I started working for BayLibre I wasn't aware that the mailserver
rewrote the sender address and so a few commits entered kernel history
with a working but unexpected address.  Map the unexpected to the intended
one.  This also makes the author of those commits (e.g.  32b4f1a
("pwm: jz4740: Another few conversions to regmap_{set,clear}_bits()"))
match the address used in the sign-off line.
