The pinmux code issues a warning if the aller attempts to disable the
lock bit in a pinmux register, since this is impossible (once it's
locked, the only way to unlock it is to reset the device/pmt controller).
The I2C/DDC/CEC/USB macros expect a lock setting to be passed in,
and the previous setting of DISABLE caused the pinmux table parsing
code to issue the warning. Changing the lock bits in these table
entries to DEFAULT (i.e. don't touch it) fixes this.
