dts: arm: ti: Use hardcoded addresses in cc32xx_launchxl.dtsi

In general we should be using hardcoded addresses in the dtsi files
rather than getting ifdef from other places.  As the unit address of the
node is typically based on the address in hex w/o the '0x' we can't just
use #defines directly.
