The original commit (a) renamed con_id for shared user clock from "sclk" to "hclk" (b) increased requested clock rate Since there is no "hclk" shared bus in tegra clock tree, this effectively disabled busy hint from USB driver, and actually reduced the bus clock (instead of increasing it). Bug 821986 sated that clock effect has not been tested. Reverting it would at least restore 80MHz bus clock limit required for USB operations.

2011-11-30tegra:otg: Fix clock disable to match ref countBitan Biswas
usbd clock is enabled during the probe and not disabled after the functionality. Due to this clock reference count is non-zero and hence usbd clock is not disabled during suspend. Fixed this by disabling clock appropriately. - Since clocks are now turned off during suspend clock needs to be enabled during fsl_udc_resume.
