We are removing struct device from the gb_connection structure in the
near future. The gb_bundle structure's struct device should be used as
a replacement.
This patch moves the raw driver to use the bundle pointer instead of the
connection pointer.

These must be exposed to external modules, like gbsim. Move them to
greybus_protocols.h file.

Print (expected-payload-size actual-payload-size), when the size doesn't
match for requests received by the module. This gives more details
required for debugging the issue.

idr and ida structures have internal memory allocated that needs to be
freed when modules are removed. So call the proper idr_destroy() or
ida_destroy() functions on the module exit path to free the memory.

This is what I get over mainline:
greybus/raw.c: In function 'gb_raw_send':
greybus/raw.c:153:2: error: implicit declaration of function 'copy_from_user' [-Werror=implicit-function-declaration]
if (copy_from_user(&request->data[0], data, len)) {

greybus/raw.c: In function 'raw_read':

if (copy_to_user(buf, &raw_data->data[0], raw_data->len)) {

Fix this by including uaccess.h.

This adds a driver that implements the greybus Raw protocol as
specified.
It preserves the message boundries by only allowing a read to receive
a "full" message, and any write() call also is passed in a single
greybus request.
Totally untested, given that we have no raw firmware or gbsim code yet.
