intel/gma: Fix typo GMBUS0 -> GMBUS1 in edid.c
This typo existed in code before rewriting for using
defines and it's clearly visible after rewrite.
Previously it was writing to reserved area of GMBUS0 register,
while values are matching those of GMBUS1.
This line probably is a no-op since it's just sending the STOP
again (without an address set this time).
