misc fixes

+ Align kernel to 2MiB boundary in u-boot

+ Optimize alignment functions a little bit, should still have to check
  on real hardware but 'feels' more clean

+ Add early boot debugging

+ Put extra cores we aren't ready to account for to sleep if/when they
  boot.

+ Make BASE_PAGE_SIZE constant on riscv64/32, helps the compiler with
  some alignment checks among other things.
