USB: EHCI: make ehci-s5p a separate driver
Separate the Samsung S5P/EXYNOS host controller driver from ehci-hcd
host code so that it can be built as a separate driver module.
This work is part of enabling multi-platform kernels on ARM;
however, note that other changes are still needed before S5P/EXYNOS can
be booted with a multi-platform kernel. We currently expect those
to get merged for 3.10.
With the infrastructure added by Alan Stern in patch 3e0232039
"USB: EHCI: prepare to make ehci-hcd a library module", we can
avoid this problem by turning a bus glue into a separate
module, as we do here for the s5p bus glue.
In V4 (arnd)
- revert some of the pointless changes.
- fix allocation of s5p specific data structure.
In V3:
- Detailed commit message added here, why this patch is required.
- MODULE_LICENSE is GPL v2.
- Added .extra_priv_size to eliminate the separate allocation of
the s5p_ehci_hcd structure and removed .reset function pointer
initialization.
- Arranged #include's in alphabetical order.
- After using extra_priv_size initialization, struct usb_hcd *hcd
is redundant and can be removed from the probe function.
- Eliminated s5p_ehci_phy_enable,contents of statements moved
into the s5p_ehci_probe
- Eliminated s5p_ehci_phy_disable, contents of statements moved into
the s5p_ehci_remove.
In V2:
- Tegra patch related changes removed from this patch.
