    drm/i915: Fix possible int overflow in skl_ddi_calculate_wrpll()
    
    On the off chance that clock value ends up being too high (by means
    of skl_ddi_calculate_wrpll() having benn called with big enough
    value of crtc_state->port_clock * 1000), one possible consequence
    may be that the result will not be able to fit into signed int.
    
    Fix this, albeit unlikely, issue by first casting one of the operands
    to u32, then to u64, and thus avoid causing an integer overflow.
    
    Found by Linux Verification Center (linuxtesting.org) with static
    analysis tool SVACE.
