Extend the serial range from 0x100 to 0x1000
The AXI UART 16550 v2.0 from Xilinx only seem to require 32 bytes for
the registes, but let's reduce the changes with the original DTS.

difference.

Let see if we can guess which is the correct number for the interrupts.
The plic should appear in the IRQ list but currently it doesn't.

This timer is present and initialized in OpenSBI and seems to drive the
UART device. Not sure if we need to see it from the kernel.
