[PATCH v2 0/7] Meson GXL/GXM USB host mode support

the goal of this series is to enable USB host mode on Meson GXL and GXM.
there are four dependencies to get this working:
1. "improvements and fixes for the phy-meson-gxl-usb2 driver" from [0]
   (this is already queued for v4.17 and part of linux-next)
2. "DWC3 support for Amlogic Meson AXG and GXL SoCs from" [1] (this is
   also queued for v4.17 and part of linux-next)
3. "initialize (multiple) PHYs for a HCD" from [3] (this is also queued
   for v4.17 and part of linux-next)
4. "Meson GXL USB3 PHY driver" from [3] (this is also queued for v4.17
   and part of linux-next)
there is a soft dependency on the following series (currently dependency
#3 from above breaks suspend on some TI SoCs, so there's a risk that #3
will get reverted if the following series doesn't fix it):
5. "fix HCD PHY suspend handling" from [4] (not queued for v4.17 yet)

select boards get USB enabled. I have tested this myself successfully
- Khadas VIM (GXL S905X)
- Le Potato (GXL S905X)
- Khadas VIM2 (GXM S912)
- a board which is similar to P230 (GXL S905D)

a user on IRC reported that Nexbox A95X (S905X) support is working fine
as well.

changes since RFC v1 at [5]:
- rebased on top of Kevin's v4.17/dt64 branch (c339f0e29ce9f9 "ARM64:
  dts: meson-gx: make efuse read-only")
- dropped RFC prefix because this was also tested and confirmed working
  by a user on IRC on his Nexbox A95X (S905X)
