refactor(lib): rename GENMASK parameters

Browse source 
Rename GENMASK parameters for better readability to avoid
misinterpreting the 'l' as '1' in BIT(l) usage.

/*
* Create a contiguous bitmask starting at bit position @l and ending at
* position @h. For example
* Create a contiguous bitmask starting at bit position @low and ending at
* position @high. For example
* GENMASK_64(39, 21) gives us the 64bit vector 0x000000ffffe00000.
