Change the cadence_uart such that tx/rx is enabled on reset. Assuming
both are enabled makes debugging early Linux kernel bootup a little bit
easier.

I've used this patch mostly for my own testing, but it may be of general
use. On a real system, I would expect the bootloader to leave the uart
in an enabled state, but I'm not using a bootloader for my testing :).
