The flash-write tool is operational. The call to read status register
from flash-host is not working yet, and that is to be solved. In the
meantime, there are sleep functions inserted where we're supposed
to poll the status register.

This reads to stdout, in binary format. With "-v" it prints text and
scans the bus too. The examples here below use the same card (and same
data) as in commit "d44ace7e

 w1: complete eeprom low-level support".

If you find this patch with "git blame" please use "git blame -w"
to have all white-space ignored while associating lines to commits.

This commit has no practical effect but cleanup. I made it
with sed like this:

  git grep -l '[ \t]$' | xargs sed -i 's/[ \t]*$//'

However, I had to manually restore doc/wrpc_mon.png after the fact.
Similarly, I restored the include/hw/*regs.h files, as they
are (most likely) auto-generated.
