[net-next,v12,0/8] TXGBE PHYLINK support

Implement I2C, SFP, GPIO and PHYLINK to setup TXGBE link.

Because our I2C and PCS are based on Synopsys Designware IP-core, extend
the i2c-designware and pcs-xpcs driver to realize our functions.

v11 -> v12:
- split I2C designware patch (2/9) to I2C tree, repost remaining 8
  patches

v10 -> v11:
- add gc->label NULL check
- rebase on merging of wangxun patches

v9 -> v10:
- clear I2C device model flags
- change the order of header files
- use xpcs_create_mdiodev()
- fix Kconfig warning

v8 -> v9:
- rename swnode property for specific I2C platform device
- add ".fast_io = true" for I2C regmap
- use raw_spinlock_t for GPIO reg lock and adjust its position
- remove redundant txgbe->mdiodev
- keep reverse x-mass tree order
- other minor style changes

v7 -> v8:
- use macro defined I2C FIFO depth instead of magic number
- fix return code of clock create failure
- add spinlock for writing GPIO registers
- implement triggering GPIO interrupts for both-edge type
- remove the condition that enables interrupts
- add mii bus check for PCS device
- other minor style changes

v6 -> v7:
- change swnode property of I2C platform to be boolean
- use device_property_present() to match I2C device data

v5 -> v6:
- fix to set error code if pointer of txgbe is NULL
- change "if" to "switch" for *_i2c_dw_xfer_quirk()
- rename property for I2C device flag
- use regmap to access I2C mem region
- use DEFINE_RES_IRQ()
- use phylink_mii_c45_pcs_get_state() for DW_XPCS_10GBASER

v4 -> v5:
- add clock register
- delete i2c-dw.h with platform data
- introduce property "i2c-dw-flags" to match device flags
- get resource from platform info to do ioremap
- rename quirk functions in i2c-designware-*.c
- fix calling txgbe_phylink_init()

v3 -> v4:
- modify I2C transfer to be generic implementation
- avoid to read DW_IC_COMP_PARAM_1
- remove redundant "if" statement
- add specific labels to handle error in txgbe_init_phy(), and remove
  "if" conditions in txgbe_remove_phy()

v2 -> v3:
- delete own I2C bus master driver, support it in i2c-designware
- delete own PCS functions, remove pma configuration and 1000BASE-X mode
- add basic function for 10GBASE-R interface in pcs-xpcs
- add helper to get txgbe pointer from netdev

v1 -> v2:
- add comments to indicate GPIO lines
- add I2C write operation support
- modify GPIO direction functions
- rename functions related to PHY interface
- add condition on interface changing to re-config PCS
- add to set advertise and fix to get status for 1000BASE-X mode
- other redundant codes remove
