Colin Ian King 64918e3f71 drm/arm: fix unintentional integer overflow on left shift 
[ Upstream commit 5f368ddea6fec519bdb93b5368f6a844b6ea27a6 ]

Shifting the integer value 1 is evaluated using 32-bit arithmetic
and then used in an expression that expects a long value leads to
a potential integer overflow. Fix this by using the BIT macro to
perform the shift to avoid the overflow.

Addresses-Coverity: ("Unintentional integer overflow")
Fixes: ad49f8602f ("drm/arm: Add support for Mali Display Processors")
