The sp7021 clock driver has its own shifted high word mask macro,
similar to the ones many Rockchip drivers have.

Remove it, and replace instances of it with hw_bitfield.h's
FIELD_PREP_WM16 macro, which does the same thing except in a common
macro that also does compile-time error checking.

This was compile-tested with 32-bit ARM with Clang, no runtime tests
were performed as I lack the hardware. However, I verified that fix
commit 5c667d5a5a3e ("clk: sp7021: Adjust width of _m in HWM_FIELD_PREP()")
is not regressed. No warning is produced.

Does it generate the same code before and after?
