USB: pxa27x_udc: check return value of clk_enable

Browse source

clk_enable() may fail according to the API contract.
Previously, udc_enable() ignored its return value and returned void.

Modify udc_enable() to return the error code. Additionally, update
all of its callers (pxa_udc_pullup, pxa_udc_vbus_session,
pxa27x_udc_start, pxa_udc_probe, and pxa_udc_resume) to check
this return value and handle the failure properly with necessary
cleanups or rollbacks.
