Initialize UART in bootrom
...
Unless the UART is properly initialized, the console won't display any
message until a next stage intializes it (OpenSBI) and then we will
start to see messages after uploading the next bootroms.
Follows the OpenSBI initialization for the UART setting the baud rate to
115200 and assuming a clock of 50 MHz.
