When building with yosys we assume hello_world fits in 8kB. There's

This commit enhances hello_world.bin output by printing
a ASCII lightbulb, which turns out to be Microwatt's logo,
instead of simply a "Hello World" text message.

Use a more generic console_init() instead of potato_uart_init(),
and do the same for interrupt control. There should be no
change in behaviour.

This uses the new header files for register definitions and
extracts the core frequency from syscon rather than hard coding it.

Shrink hello_world a bit (from 12kB to 8kB).
