[wireless-next,00/11] using calculate_bit_shift() to fix undefined bitwise shift behavior.

Message

There is an undefined bitwise shift behavior, when the right operand is
greater than or equal to then width of the  promoted left operand.
(eg: (u32)data << 32). Commit bc8263083af6("fix an undefined bitwise shift
behavior") only fixed one problem, there are many similar problems in 
drivers/net/wireless/realtek/. 

This patchset adds a new function calculate_bit_shift() to fix the
remaining undefined bitwise shift behavior problems.(Compile tested only)
