[PATCH -mm] aty128_decode_var gcc 4.1 warning fix

[Daniel Walker <dwalker@mvista.com>]

It appears to be possible to get a random post divider, if aty128_var_to_pll()
doesn't find one in the table .. Needs review .

Fixes the following warning,

drivers/video/aty/aty128fb.c: In function â??aty128_decode_varâ??:
drivers/video/aty/aty128fb.c:1516: warning: â??pll.post_dividerâ?? may be used uninitialized in this function
