    drm/omap: fix i886 work-around · 0c43f1e0

    7d267f06 ("drm/omap: work-around for
    errata i886") changed how the PLL dividers and multipliers are
    calculated. While the new way should work fine for all the PLLs, it
    breaks omap5 PLLs. The issues seen are rather odd: seemed that the
    output clock rate is half of what we asked. It is unclear what's causing
    there issues.
    
    As a work-around this patch adds a "errata_i886" flag, which is set only
    for DRA7's PLLs, and the PLL setup is done according to that flag.
