ARM: OMAP: USB: EHCI and OHCI hwmod structures for OMAP3
Following 2 hwmod structures are added
1. usb_host_hs
The hwmod of usbhs with uhh, ehci and ohci base addresses
functional clock and ehci, ohci irqs
2. usb_tll_hs
hwmod of usbhs with the TLL base address and irq.

[paul@pwsan.com: fixed whitespace; removed nonexistent TLL->L3 interface;
added master & slave for L4 CORE->TLL interface; skip registration on
3430ES1; fixed multiline comment style; updated to apply on Tony's cleanup
branch; rebased]

|

* In the following configuration :
|
||||
* - USBHOST module is set to smart-idle mode
|
||||
* - PRCM asserts idle_req to the USBHOST module ( This typically
|
||||
* happens when the system is going to a low power mode : all ports
|
||||
* have been suspended, the master part of the USBHOST module has
|
||||
* entered the standby state, and SW has cut the functional clocks)
|
||||
* - an USBHOST interrupt occurs before the module is able to answer
|
||||
* idle_ack, typically a remote wakeup IRQ.
|
||||
* Then the USB HOST module will enter a deadlock situation where it
|
||||
* is no more accessible nor functional.
|
||||
*
|
||||
* Workaround:
|
||||
* Don't use smart idle; use only force idle, hence HWMOD_SWSUP_SIDLE

* When the USBHOST module is set to smart-standby mode, and when it is

* ready to enter the standby state (i.e. all ports are suspended and

||||
* all attached devices are in suspend mode), then it can wrongly assert
|

* the Mstandby signal too early while there are still some residual OCP
|

* transactions ongoing. If this condition occurs, the internal state

* machine may go to an undefined state and the USB link may be stuck

* upon the next resume.
