drm/msm: Fix wrong size calculation
commit 0a727b459ee39bd4c5ced19d6024258ac87b6b2e upstream.
For example, memory-region in .dts as below,
reg = <0x0 0x50000000 0x0 0x20000000>
We can get below values,
struct resource r;
r.start = 0x50000000;
r.end = 0x6fffffff;
So the size should be:
size = r.end - r.start + 1 = 0x20000000
