Fix W=1 about variables assigned but never used. - One variable is only used when CONFIG_FB_ATY_GENERIC_LCD is defined Fix so variable is only defined with CONFIG_FB_ATY_GENERIC_LCD - Several variables was only assigned by a call to aty_ld_le32(). Drop the variables but keep the call to aty_ld_le32() as it may have unexpected side-effects.
