UPSTREAM: net: Add eth phy generic driver for shared MDIO
For dual ethernet controllers, the HW design may connect ETH phys to
one MDIO ports. So two different ethernet drivers have to share MDIO bus.
Since two ethernet drivers are independent, we can't ensure their probe
order.
To resolve this problem, introduce an eth phy generic driver and uclass.
After eth-uclass binds, we search the mdio node and binds the phy node
with the eth-phy-generic driver.
When one eth driver get its phy device, the parent of phy device will
probe prior than phy device. So this ensure the eth driver ownes the
MDIO bus will be probed before using its MDIO.

Handle slow MMC writes
Flashing a 400Mb sparse system image takes ~10 minutes. The fastboot UDP
protocol expects a response within 1 minute, so during long flash
operations, the device must send fastboot "INFO" packets.
This patch does the following:
- Separate large writes into writes of size FASTBOOT_MAX_BLK_WRITE.
This parameter was tuned by hand to result in a ~10 second write.
- Keep a timer and send an INFO packet every 30 seconds.
- Adjust the sequence number in the header of the fastboot OKAY packet
to account for any INFO packets sent during flashing.
- Reduce busywaiting in the bcm2835 MMC driver. This change is based on
what the kernel does, and doesn't seem to corrupt the MMC. Without
this change, "flashall" takes 25 minutes.
Bug: 31887729
Test: "fastboot -s udp:$RPI_IP flashall" works, rpi3 boots
- Compute CRC checksum over every write to verify written data
was not corrupted.

Implement fastboot continue, reboot, reboot-bootloader, boot.
Add functions to respond to fastboot continue, reboot, and
reboot-bootloader. Continue continues the normal android boot process.
Reboot-bootloader writes a message to the start of the fastboot
buffer, to be parsed at the start of the android boot process. Boot
boots the previously downloaded image from memory.
Bug: 31887729
Test: - Sending "continue" boots into android.
- Sending "reboot" reboots the device.
- Sending "reboot-bootloader" reboots the device, and the
message persists in memory.
- Sending "boot boot.img" boots into kernel.

Implement fastboot flash and erase.
Add function to respond to fastboot flash and erase. Flash writes the
previously downloaded image to indicated partition. Erase clears the
indicated partition. fb_flash and fb_erase are essentially wrappers
for fb_mmc_flash_write and fb_mmc_erase, which are implemented in
common/fb_mmc.c.
Added common/fb_common.c, where fastboot_okay/fail are implemented.
common/fb_mmc.c assumes fasboot_okay() and fastboot_fail() are
implemented, but they were tied to the fastboot USB implementation.
This refactor adds the response string as a parameter to
fastboot_okay/fail, instead of modifying a global.
Bug: 31887729
Test: FLASH:
- Create file "foo" containing 2048 chars = "-"
- Start "fastboot udp" on device and run
"fastboot -s udp:$RPI_IP flash misc foo" from host
- From U-boot console, read into memory the first 4 blocks from
misc partition, observe each byte is "-".
ERASE
- Start "fastboot udp" on device and run
"fastboot -s udp:$RPI_IP erase misc" from host
- From U-boot console, read into memory many blocks from misc
partition, observe each byte is 0x00
Configs that use fastboot USB implementation still build.
