The TI DP83822 does have support for configurable RGMII RX/TX clock
shift, add support for parsing DT properties which describe the RX/TX
clock shift configuration and configuration of the matching bits in
RCSR register.
The shift is only configurable on DP83822, the other PHYs supported
by this PHY driver, namely DP83825/DP83826 variants, do not implement
this functionality and the RCSR bits used to configure the clock shift
are missing from those PHYs.
The shift is configurable separately for RX and TX path. Each path can
either enable the shift or disable the shift using single bit. In case
the shift is disabled, a delay of 0ns is added to the path, otherwise
a delay of 3.5ns is added to the path.
Note that the two RCSR bits 11 and 12 have inverted logic, RCSR bit 12
enables RX internal shift when SET, while RCSR bit 11 enables TX shift
when UNSET.

Convert PHY driver to U_BOOT_PHY_DRIVER() macro and drop phy_register() init call.
Converted using sed
"s@^static struct phy_driver \(.*\)_driver = \+{@U_BOOT_PHY_DRIVER(\L\1) = {"
This particular PHY driver is slightly more spread out across additional
source files. Since the phy_register() calls are no longer necessary, all
the registration calls across those source files is dropped. Furthermore,
the Makefile can now be updated to only compile generic TI PHY support if
matching Kconfig symbol is enabled and the ifdeffery in the generic TI PHY
driver can be dropped.

This driver is based on an older downstream TI kernel, with
changes and cleanups to work with mainline device-tree bindings.

ti_phy_init function was allocated to the DP83867 PHY. This function
name is to generic for a specific PHY. The function can be moved to a
TI specific file that can register all TI PHYs that are defined in the
defconfig. The ti_phy_init file will contain all TI PHYs initialization
so that only phy_ti_init can be called from the framework.
In addition to the above the config flag for the DP83867 needs to be changed
in the Kconfig and dependent defconfig files. The config flag that was
used for the DP83867 was also generic in nature so a more specific
config flag for the DP83867 was created.
