Arnd Bergmann 2d94cffc94 soc: ixp4xx/qmgr: fix invalid __iomem access
commit a8eee86317f11e97990d755d4615c1c0db203d08 upstream.

Sparse reports a compile time warning when dereferencing an
__iomem pointer:

drivers/soc/ixp4xx/ixp4xx-qmgr.c:149:37: warning: dereference of noderef expression
drivers/soc/ixp4xx/ixp4xx-qmgr.c:153:40: warning: dereference of noderef expression
drivers/soc/ixp4xx/ixp4xx-qmgr.c:154:40: warning: dereference of noderef expression
drivers/soc/ixp4xx/ixp4xx-qmgr.c:174:38: warning: dereference of noderef expression
drivers/soc/ixp4xx/ixp4xx-qmgr.c:174:44: warning: dereference of noderef expression

Use __raw_readl() here for consistency with the rest of the file.
This should really get converted to some proper accessor, as the
__raw functions are not meant to be used in drivers, but the driver
has used these since the start, so for the moment, let's only fix
the warning.
