Colin Ian King d26cbdd27f platform/surface: fix potential integer overflow on shift of a int 
The left shift of int 32 bit integer constant 1 is evaluated using 32 bit
arithmetic and then passed as a 64 bit function argument. In the case where
func is 32 or more this can lead to an oveflow.  Avoid this by shifting
using the BIT_ULL macro instead.

Addresses-Coverity: ("Unintentional integer overflow")
Fixes: fc00bc8ac1 ("platform/surface: Add Surface ACPI Notify driver")
