AM335x and TI81xx platform has dual musb controller so updating the
musb_dspc.c to support the same.
Changes:
- Moved otg_workaround timer to glue structure
- Moved static local variable last_timer to glue structure
- PHY on/off related cleanups

we are compiling the driver always with full OTG
capabilities, so that board_mode trick becomes
useless.

nop-usb-xceiv was polluting otg.h with its own
function prototypes. Move those prototypes to
a nop-usb-xceiv.h header.

The clock need to be enabled before the musb_core platform device is
created and registered.

We are overwriting the resource->name to "mc" so that musb_core.c
can understand it but this is also changing the platform device's
resource->name as the "name" address remains same.
Fixing the same by changing the resource->name field of local
structure only.

usb_get_phy will return -ENODEV if it's not able to find the phy. Hence
fixed all the callers of usb_get_phy to check for this error condition
instead of relying on a non-zero value as success condition.

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.

TI81XX platform has two musb interfaces and uses CPPI4.1 DMA engine.
It has builtin USB PHYs as AM35x. The current set of patches adds support
for one instance and only in PIO mode.
