Anand Gadiyar 9b43cffbbd USB: ehci: omap: use default interrupt threshold
The current driver reduces the interrupt threshold to 1 microframe.
This was an accidental change and is not really required.
The default of 8 microframes will do just fine. So change it back.

Ajay Kumar Gupta 8811426606 usb: host: ehci: adding regulator framework in ehci-omap.c driver.
OMAP3 has three HS USB ports so it can have three different regulator
for each PHY connected to each port.

Currently these regulators are assumed to be optional and driver doesn't
fail but continue with the initialization if it doesn't get any regulators.

Regulator supply names has to be mapped in board files as 'hsusbN' where
'N' is port number and can be {0, 1 ,2}.
