When rtlwifi is built for the sh4 architecture, build errors of the following
type occur. As these raw port accesses are specific to the X86 architecture,
their usage is restricted and dummy routines are substituted for all other
platforms.

    v3.0/sh4/sh-allmodconfig v3.0/sh4/sh-allyesconfig
src/drivers/net/wireless/rtlwifi/rtl8192c/../pci.h:290: error: implicit declaration of function 'outl': 4 errors in 2 logs
