Subject: [PATCH] MIPS: ralink: make RALINK_ILL_ACC symbol visible

The illegal access driver is optional - it is informational and does not
provide critical functionality. Furthermore, it is currently not
functional on RT5350 SoCs, so a user may choose to omit non-functional
code on that platform. The default is kept at 'y' for backwards
compatibility. This change only makes the symbol visible and adds a
brief description.
