With this scheme, an IO can be controlled both by the cpu running linux and the Island processor. This provides great flexibility to re-purpose the Island IOs for regular TLMM usecases. 2 new bits are added to ctl_reg, egpio_present is a read only bit which shows if egpio feature is available or not on a given gpio. egpio_enable is the read/write bit and only effective if egpio_present is 1. Once its set, the Island IO is controlled from Chip TLMM. egpio_enable when set to 0 means the GPIO is used as Island Domain IO. To support this we add a new function 'egpio' which can be used to set the egpio_enable to 0, for any other TLMM controlled functions we set the egpio_enable to 1.
