commit ffb92ce826fd801acb0f4e15b75e4ddf0d189bde upstream.

Patch series "Fixes for ARCH=hexagon allmodconfig", v2.

This series fixes some issues noticed with ARCH=hexagon allmodconfig.

This patch (of 3):

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.
