This patch populates the PCI bus info in the ethtool driver query data.

Users will be able to view PCI bus info using 'ethtool -i <interface>'.

The current IP register MAC_HW_Feature1[ADDR64] only defines
32/40/64 bit width, but some SOCs support others like i.MX8MP
support 34 bits but it maps to 40 bits width in MAC_HW_Feature1[ADDR64].
So overwrite dma_cap.addr64 according to HW real design.

Adding reference clock (1us tic) for all LPI timer on Intel platforms.
The reference clock is derived from ptp clk. This also enables all LPI

Add option in plat_stmmacenet_data struct to enable VLAN Filter Fail
Queuing. This option allows packets that fail VLAN filter to be routed
to a specific Rx queue when Receive All is also set.

When this option is enabled:
- Enable VFFQ only when entering promiscuous mode, because Receive All
  will pass up all rx packets that failed address filtering (similar to
  promiscuous mode).
- VLAN-promiscuous mode is never entered to allow rx packet to fail VLAN
  filters and get routed to selected VFFQ Rx queue.

This patch is to enable Intel SERDES power up/down sequence. The SERDES
converts 8/10 bits data to SGMII signal. Below is an example of
HW configuration for SGMII mode. The SERDES is located in the PHY IF
in the diagram below.

<-----------------GBE Controller---------->|<--External PHY chip-->
+----------+         +----+            +---+           +----------+

PHY IF configuration and status registers are accessible through
mdio address 0x15 which is defined as mdio_adhoc_addr. During D0,
The driver will need to power up PHY IF by changing the power state
to P0. Likewise, for D3, the driver sets PHY IF power state to P3.

Adds the initial hooks for TBS support. This needs a 32 byte descriptor
in order for it to work with current HW. Adds all the logic for Enhanced
Descriptors in main core but no HW related logic for now.

Changes from v2:
- Use bitfield for TBS status / support (Jakub)
- Remove unneeded cache alignment (Jakub)
- Fix checkpatch issues

Before this change of_get_phy_mode() returned an enum,
phy_interface_t. On error, -ENODEV etc, is returned. If the result of
the function is stored in a variable of type phy_interface_t, and the
compiler has decided to represent this as an unsigned int, comparision
with -ENODEV etc, is a signed vs unsigned comparision.

Fix this problem by changing the API. Make the function return an
error, or 0 on success, and pass a pointer, of type phy_interface_t,
where the phy mode should be stored.

v2:
Return with *interface set to PHY_INTERFACE_MODE_NA on error.
Add error checks to all users of of_get_phy_mode()
Fixup a few reverse christmas tree errors
Fixup a few slightly malformed reverse christmas trees

v3:
Fix 0-day reported errors.
