USB: Add config option to call ehci_hcd_init() again after EHCI reset
This patch adds the config option CONFIG_EHCI_HCD_INIT_AFTER_RESET to call ehci_hcd_init() again after ehci_reset() is executed. This is needed for the upcoming VCT EHCI support which needs to re-init the hcd part again after the EHCI CMD_RESET is executed.
