musb_hdrc: Fix TUSB6010 ID register offsets.

[Sorry, the previous patch was a copy/paste mistake, this one should be
better]

I have no access to the docs for this chip but I'm pretty sure the current
address of the two DIDR1 registers is wrong because it's outside the
TUSB-specific register space.  The modified address in turn has a good
chance to be correct.
