When I assign GRNLED_SEL=1, it affects the state of MMCPOWER.

It would be nice to see ALL of your initialization/setup source code which includes showing the include file(s) you are using.
Also post the portion of the LISTing file around the instructions you posted so we can see what the compiler is doing.

Also read about the fast I/O if the fast I/O is not selected then setting a port's bit might change the Tris register.

You're probably having a RMW problem. Try doing all operations
on the latch, instead of the port. That should eliminate the problem.
Change the definition of the Green LED bit to use the Latch. Example:
#bit GRNLED_SEL = LATF.2
