When building ARCH=hexagon allmodconfig, the following errors occur:

ERROR: modpost: "__raw_readsl" [drivers/i3c/master/svc-i3c-master.ko] undefined!
ERROR: modpost: "__raw_writesl" [drivers/i3c/master/dw-i3c-master.ko] undefined!
ERROR: modpost: "__raw_readsl" [drivers/i3c/master/dw-i3c-master.ko] undefined!
ERROR: modpost: "__raw_writesl" [drivers/i3c/master/i3c-master-cdns.ko] undefined!
ERROR: modpost: "__raw_readsl" [drivers/i3c/master/i3c-master-cdns.ko] undefined!

Export these symbols so that modules can use them without any errors.

Fixes: 013bf24c3829 ("Hexagon: Provide basic implementation and/or stubs for I/O routines.")

It would be nice if this could get into 5.14 at some point so that we
can build ARCH=hexagon allmodconfig in our CI.
