While removing g_file_storage, we also had to fix a bunch

There's a big series getting us closer to being able to

Other than that there's the usual typo fixes and miscelaneous

This reverts commit d8c3ef256f.
Above mentioned change was made along with multi usb phy change and
adding DT support for nop transceiver. But other two changes did not
make it to mainline. This in effect makes dsps musb wrapper unusable
even for single instance.
Hence revert it so that at least single instance can be supported.

am335x uses nop transceiver driver and need to enable builtin phy
by writing into usb_ctrl register available in system control
module register space. This is being added at musb glue driver
layer until a separate system control module driver is available.
Proper solution is to make use of control module driver, but it is
not expected to be ready soon.
Other options available are providing control module register space
as memory resource via DT or using omap hwmod.
DT approach has been rejected by Rob Herring, while resources are
being moved from hwmod to DT. And both of the above approaches
require that control module registers be configured in wrapper
itself requring a quirk in driver as well as DT or hwmod.
Here another option is used, providing driver with control module
register physical address. Even though this a hack, there is no other
option left till control module driver is ready. As of now only
am335x is using dsps wrapper, and so driver is made aware of am335x
control module physical address.
Please note that this is a temporary arrangment till omap control
module driver is available.

Currently multiple phy's of the same type are not supported, hence
reduce musb instances to one. This helps in supporting at least one
instance of musb, rather than having none. Even without this, it was
observed that both instances were working (by luck), but this holds
good iff wrapper is part of Image. And it is not correct for both
controller's to be associated with same phy, here it was working
because phy is a nop one. And having wrapper as a module and
rmmod'ing would crash.
This can be reverted once multi phy support for same type is available
and driver is enhanced to make use of it.

This replaced the handcrafted id handling by the PLATFORM_DEVID_AUTO

This patch probably also fixes ux500 because I did not find the "musbid"
variable to remove. And we close a tiny-unlikely race window becuase the
old code gave the id back before device was destroyed in the remove
case.

platform_device_unregister() only calls platform_device_del() and
platform_device_put(), thus use platform_device_unregister() to
simplify the code.
Also the documents in platform.c shows that platform_device_del
and platform_device_put must _only_ be externally called in error
cases. All other usage is a bug.

Here we have a bunch of miscellaneous cleanups and fixes

We are finally improving OMAP's VBUS/ID Mailbox usage so
that we can introduce our PHY drivers properly. Also, we're
adding support for multiple instances of the MUSB IP in
the same SoC, as seen on some platforms from TI which
have 2 MUSB instances.
Other than that, we have some small fixes like not kicking
DMA for a zero byte transfer, or properly handling NAK timeout
on MUSB's host side, and the enabling of DMA Mode1 for any
transfers which are aligned to wMaxPacketSize.
All patches have been pending on mailing list for a long time

nop xceiv got its own header to avoid polluting otg.h. It has also
learned to work as USB2 and USB3 phys so we can use it on USB3
controllers.
Together with those two changes to nop xceiv, we're adding basic
PHY support to dwc3 driver, this is to allow platforms which actually
have a SW-controllable PHY talk to them through dwc3 driver.
We're adding a new phy driver for the OMAP architecture. This driver
is for the PHY found in OMAP4 SoCs, and a new phy driver for the
marvell architecture. An extra phy driver - for Tegra SoCs - is now
moving from arch/arm/mach-tegra* to drivers/usb/phy.

Add a linked list for keeping multiple PHY instances with different
types so that we can have separate USB2 and USB3 PHYs on one single
board. _get_phy_ has been changed so that the controller gets
the transceiver by type. _remove_phy_ has been added to let the phy
be removed from the phy list.

_transceiver() in otg.c is replaced with _phy. usb_set_transceiver is
replaced with usb_add_phy to make it similar to other usb standard
function names like usb_add_hcd.
