1959930462 usb: host: ehci-st: Inform the reset framework that our reset line may be shared 
On the STiH410 B2120 development board the ST EHCI IP shares its reset
line with the OHCI IP.  New functionality in the reset subsystems forces
consumers to be explicit when requesting shared/exclusive reset lines.

e47c5a0906 usb: host: ehci-st: Add EHCI support for ST STB devices 
This patch adds the glue code required to ensure the on-chip EHCI
controller works on STi consumer electronics SoC's from STMicroelectronics.

It mainly manages the setting and enabling of the relevant clocks and manages
the reset / power signals to the IP block.
