'pf' and 'lut' is just difference name in difference chips, but basic it is
a MMIO base address plus an offset.
Rename it to avoid duplicate pf_* and lut_* in driver.

PCIE_PME_TO_L2_TIMEOUT_US before asserting the SoC specific PMXMTTURNOFF
bit to complete the PME_Turn_Off handshake. This link would then enter
L2/L3 state depending on the VAUX supply.
In the resume path, the link is brought back from L2 to L0 by doing a
software reset.

ls1043a add suspend/resume support.
Implement ls1043a_pcie_send_turnoff_msg() to send PME_Turn_Off message.
Implement ls1043a_pcie_exit_from_l2() to exit from L2 state.

drivers/pci/controller/
ls1021a add suspend/resume support.
Implement callback ls1021a_pcie_send_turnoff_msg(), which write scfg's
SCFG_PEXPMWRCR to issue PME_Turn_off message.
Implement ls1021a_pcie_exit_from_l2() to let controller exit L2 state.

Notes:
Change from v2
Since difference SoCs require different sequence for exiting L2, let's add
a separate "exit_from_l2()" callback. This callback can be used to execute
SoC specific sequence.
