UPSTREAM: usb: ehci: Fix accessors for big-endian platforms and descriptors

Commit 9000eddbae0d ("drivers/usb/ehci: Use platform-specific accessors")
broke USB 2.0 on big-endian platforms because for them writel/readl()
does automatic conversion of BE data to LE.

Proper implementation requires to use "raw" variant of these accessors
which read/write data without messing with endianess.

While at it replace cpu_to_be32() to be32_to_cpu() in readl() to
keep sane semantics.

drivers/usb/ehci: Use platform-specific accessors

Current implementation doesn't allow utilization of platform-specific
reads and writes.

But some arches or platforms may want to use their accessors that do
some extra work like adding barriers for data serialization etc.

Interesting enough OHCI accessors already do that so just aligning
EHCI to it now.

This is a resend of http://patchwork.ozlabs.org/patch/726714/
Back in the day this patch broke some PPC and Sandbox boards
as they we missing inclusion of "asm/io.h". Those missing items were
fixed with:
1) http://patchwork.ozlabs.org/patch/751397/
2) http://patchwork.ozlabs.org/patch/771099/

So now it should be safe to apply this patch.
FWIW TravisCI builds everything with all 3 patches in place,

usb: ehci: remember init mode

When an EHCI device is registered in device mode, the HW isn't actually
initialized at all, and hence isn't left in a running state. Consequently,
when the device is deregistered, ehci_shutdown() will fail, since the HW
bits it expects to see set in response to its shutdown requests will not
be sent, and the message "EHCI failed to shut down host controller." will
be printed.

Fix ehci-hcd.c to remember whether the device was registered in host or
device mode, and only call ehci_shutdown() for host mode registrations.

dm: usb: Refactor EHCI init

Move the bulk of the code in usb_lowlevel_init() into a separate function
which will also be used by driver model. Keep the CONFIG options out of
this function by providing a tweak flag for Faraday. We need to avoid using
CONFIG options in driver model code where possible, since it makes it
impossible to use multiple controllers in that code where they have
different options.

The CONFIG_EHCI_HCD_INIT_AFTER_RESET option is also kept out of the
common init function. With driver model the controller will be able to
perform this extra init itself after registering with the EHCI layer.
