Dan Kalowsky a6f9d1a7b8 Renaming K_mvdreq to _k_movedata_request
Updating micro kernel functions to follow a consistent naming convention.
Part of that process is the removal of camelCase naming conventions for the
preferred_underscore_method.

Change accomplished with the following script:

#!/bin/bash
echo "Searching for ${1} to replace with ${2}"

echo "Checking C, CPP, H, HPP, and s files..."
find . -type f \( -iname \*.[ch] -o -iname \*.[ch]pp -o -iname \*.s \) \
       -not \( -path host/src/genIdt -prune \) \
       -not \( -path host/src/gen_tables -prune \) \
       -print | xargs sed -i "s/"${1}"/"${2}"/g"

echo "Checking KCONF, LST, and PY files..."
find . -type f \( -iname \*.lst -o -iname \*.kconf -o -iname \*.py \) \
       -not \( -path host/src/genIdt -prune \) \
       -not \( -path host/src/gen_tables -prune \) \
       -print | xargs sed -i "s/"${1}"/"${2}"/g"
