hw/display/framebuffer: Add cast to force 64x64 multiply

In framebuffer_update_display(), Coverity complains because we
multiply two values of type 'int' (which will be done as a 32x32
multiply and so in theory might overflow) and then add the result to
a ram_addr_t, which can be 64 bits.

4GB framebuffers are not plausible anyway, but keep Coverity happy
by adding casts which force these multiplies to be done as 64x64.
