- remove mx6_usb_dr_init() in board specific initialization files
- Add module_init(mx6_usb_dr_init) and module_exit(mx6_usb_dr_exit)
in usb_dr.c to support the usb_dr modulization
- Export necessary function which is used in usb_dr.c

MSL part
- For HSIC, not connect nor disconnect, then WKCN,
WKDC must not be set during suspend
- For HSIC, must set bit 21 in host control registry
after device connected to host controller
- USB PHY 480M clock output must turn on to avoid about
10ms delay before sending out resume signal
- HW_ANA_MISC clkgate delay must be set to 2 or 3 to
avoid 24M OSCI not stable issue

MSL part
Add HSIC support for Host2 and Host3, for HSIC mode, there
is not usb phy needed, the usb device is always at the board
- Validation hardware: iMX6Q Validation Port Card and Re-worked
Rev X3 board, for hardware rework detail, contact Ken Sun (b03826)
- Validation device: HSIC interface SMSC HUB(USB4640) and Host 3.
Host 2 is coding finishes, but not verified due to hardware limitation.
- Pin Conflict with Ethernet, order to use HSIC, the user need
disable ethernet function at both u-boot and linux kernel.
For u-boot: please undefine CONFIG_MXC_FEC at your board config file
For kernel: please define CONFIG_USB_EHCI_ARC_HSIC, the entry is:
Device Drivers---> USB support---> Support HSIC Host controller
for Freescale SoC
- Suspend/resume and wakeup are not supported due to IC issues,
these IC issues will be fixed at TO1.1 for i.mx6, software will
add these support after receiving TO1.1 chip.
