Add support for xcompiler on Alpine 3.13
...
Problem: xcompiler on Alpine 3.13 was not found
Solution is to add "riscv-none-elf-gcc":
1. Add Edge to your repositories:
$ echo -e "http://dl-cdn.alpinelinux.org/alpine/edge/main\nhttp://dl-cdn.alpinelinux.org/alpine/edge/testing\nhttp://dl-cdn.alpine
linux.org/alpine/edge/community" >> /etc/apk/repositories
$ apk update
$ apk add gcc-riscv-none-elf
2. The xcompiler should be found at:
$ which riscv-none-elf-gcc
/usr/bin/riscv-none-elf-gcc

software/liblitedram: Improve find_cmd_delay to favor higher number of valid modules and centered scan.
...
Also add an optional debug #define to look at cmd/clk centering scans:

soc: Add init_rom to initialize ROM and contents and with auto_size option (enable by default) to reduce ROM size to length of contents when in Read Only mode.
...
This ensures the integrated ROM is reduced to minimal size before build and avoid having to adjust it manually with --integrated-rom-size on targets.

xics: Disable endianness swapping
...
The endianess swapping code caused the core to diverge from microwatt resulting in:
- The xics tests not working as-is: https://github.com/antonblanchard/microwatt/blob/master/tests/xics/xics.h
- byte writes writing to the incorrect byte
This removes endianswapping and minimizes the delta from upstream for the xics irq.h header.
