[PATCH xf86-video-mga 2/2] Add const qualifier to char *from in MGAdoDDC

[Alan Coopersmith]

Only used to store arguments to pass as printf %s strings to xf86DrvMsg

Fixes gcc warnings:
mga_driver.c: In function 'MGAdoDDC':
mga_driver.c:1338:7: warning: assignment discards qualifiers from pointer target type
mga_driver.c:1343:11: warning: assignment discards qualifiers from pointer target type
mga_driver.c:1351:8: warning: assignment discards qualifiers from pointer target type
mga_driver.c:1359:8: warning: assignment discards qualifiers from pointer target type
