Jason-JH.Lin 96312a251d drm/mediatek: Fix coverity issue with unintentional integer overflow
[ Upstream commit b0b0d811ea ]

1. Instead of multiplying 2 variable of different types. Change to
assign a value of one variable and then multiply the other variable.

2. Add a int variable for multiplier calculation instead of calculating
different types multiplier with dma_addr_t variable directly.
