net: ipa: move channel type values into "gsi_reg.h"
The gsi_channel_type enumerated type define values used for the channel type/protocol for event rings and channels. Move its definition out of "gsi.c" and into "gsi_reg.h", alongside the definition of the CH_C_CNTXT_0 register offset and its fields. Add a comment near the definition of the EV_CH_E_CNTXT_0 register indicating this type is used for its EV_CHTYPE field.
