This patchset add the fastboot support for rk3288, and I have tested on
firefly-rk3288 board.
Summary of changes in this series:
- Rework the behaviour in otg_phy_init() and otg_phy_off()
- Achieve the regs_phy from DT
- Update comments a little

So far, Rockchip SoCs have two kinds of USB2.0 phy, like Synopsys and
Innosilicon. This patch applys dwc2 usb driver framework to implement
phy_init and phy_off for Synopsys phy on Rockchip platform.

The total FIFO size of dwc2 on Rockchip SoCs is shorter than the
existen, so re-define them to fit Rockchip SoCs.

Enable fastboot feature on rk3288.
This path doesn't support the fastboot flash function command entirely.
We will hit "cannot find partition" assertion without specified
partition environment. Define gpt partition layout in specified board
such as firefly-rk3288, then enjoy it!

That isn't terrible future proof ... the GRF offsets are different for on
every Rockchip soc using that phy.
We do have the phy nodes in the devicetree, so shouldn't all that be
readable from there somehow?

Yup, it makes sense to me.
dwc2 usb driver didn't apply the devicetree model in u-boot, it's too
prolix to get phy_offset from DT. hmm, I have fixed it, and pass it via
regs_phy field.
Thanks!
