The separate GPHY Firmware loader driver is not used any more, the GPHY
firmware is now loaded by the GSWIP switch driver which also makes use
of the GPHY.
Remove the old unused GPHY firmware loader driver.
The GPHY firmware is useless without an Ethernet and switch driver, it
should not harm if loading this does not work for system using an old
device tree.
I am not aware of any vendor separating the device tree from the kernel
binary, it should be ok to remove this.
The code and the functionality form this separate GPHY firmware loader
was added to the gswip driver in commit 14fceff4771e ("net: dsa: Add
Lantiq / Intel DSA driver for vrx200")

While doing a global software reset, these bits are not cleared and let
some bootloader fail to initialise the GPHYs. The bootloader don't
expect the GPHYs in reset, as they aren't during power on.
The asserts were a workaround for a wrong syscon-reboot mask. With a
mask set which includes the GPHY resets, these resets aren't required
any more.

Compared to the old xrx200_phy_fw driver the new version has multiple
enhancements. The name of the firmware files does not have to be added
to all .dts files anymore - one now configures the GPHY mode (FE or GE)
instead. Each GPHY can now also boot separate firmware (thus mixing of
GE and FE GPHYs is now possible).
The new implementation is based on the RCU syscon-mfd and uses the
reeset_controller framework instead of raw RCU register reads/writes.

Instead of hacking the configuration of the FPI bus into the arch code
add an own bus driver for this internal bus. The FPI bus is the main
bus of the SoC. This bus driver makes sure the bus is configured
correctly before the child drivers are getting initialized. This driver
will probably also be used on different SoCs later.
