Refactor FPE implementation by moving common code for DWMAC4 and
DWXGMAC into a separate FPE module.

FPE implementation for DWMAC4 and DWXGMAC differs only for:
1) Offset address of MAC_FPE_CTRL_STS and MTL_FPE_CTRL_STS
2) FPRQ(Frame Preemption Residue Queue) field in MAC_RxQ_Ctrl1
3) Bit offset of Frame Preemption Interrupt Enable

Tested on DWMAC CORE 5.20a and DWXGMAC CORE 3.20a

Changes in v3:
  1. Drop stmmac_fpe_ops and refactor FPE functions to generic version to
  avoid function pointers
  2. Drop the _SHIFT macro definitions

Changes in v2:
  1. Split patches to easily review
  2. Use struct as function param to keep param list short
  3. Typo fixes in commit message and title
