mei: make host csr and me csr internal to hw-me
Move csr reading into me hardware functional calls. Since we gave up on registers caching we remove some of the unnecessary queries in mei_hw_init ane mei_reset functions. We add mei_hw_config function to wrap up host buffer depth configuration. Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
