[RFC 0/8] usb: phy: msm: various cleanups

[Arnd Bergmann <arnd@arndb.de>]

I stumbled over this warning last week, which showed up after I had
removed an incorrect patch from my randconfig build setup:

drivers/usb/phy/phy-msm-usb.c: In function 'msm_otg_probe':
drivers/usb/phy/phy-msm-usb.c:1735:14: error: 'regs[0].consumer' may be used uninitialized in this function [-Werror=maybe-uninitialized]
  motg->vddcx = regs[0].consumer;
  ~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~
drivers/usb/phy/phy-msm-usb.c:1736:14: error: 'regs[1].consumer' may be used uninitialized in this function [-Werror=maybe-uninitialized]
  motg->v3p3  = regs[1].consumer;
  ~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~
drivers/usb/phy/phy-msm-usb.c:1737:14: error: 'regs[2].consumer' may be used uninitialized in this function [-Werror=maybe-uninitialized]
  motg->v1p8  = regs[2].consumer;
  ~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~

Having already fixed the same problem in the phy-qcom-8x16-usb.c
driver before, I tried to do the same thing here, but it turned
out to be somewhat different, and I ended up running into several
unrelated issues in the driver that I now try to fix up.

The series is not tested beyond verifying that it no longer causes
randconfig warnings, and some patches are not entirely obvious.
In particular the ehci-msm and chipidea changes are probably a
good idea, but they actually change the behavior of the drivers
in a way that I cannot verify through inspection alone. The
last patch in the series probably requires some changes to the
devicetree files to go along with it.

Please have a look and test this, provided the patches make sense
conceptually.

  usb: phy: move msm_hsusb.h into driver
  usb: ehci-msm: call usb_phy_init instead of open-coding it
  usb: chipidea: msm: remove open-coded phy init
  usb: phy: move TCSR driver into new file
  usb: phy: msm: move register definitions into driver
  usb: phy: qcom: use bulk regulator interfaces
  usb: phy: msm: remove v1p8/v3p3 voltage setting
  usb: phy: msm: disable regulator for remove()
