usb: Clear CMD_RUN while issuing CMD_RESET in ehci_reset()
This patch fixes a problem noticed on lwmon5 (PPC440EPx) using the
common EHCI driver, when "usb reset" is issued multiple times.
Upon the 2nd (and further) "usb reset" command, the command fails
with the following messages:
=> usb reset
(Re)start USB...
USB: Register 1111 NbrPorts 1
USB EHCI 1.00
scanning bus for devices... 5 USB Device(s) found
scanning bus for storage devices... 2 Storage Device(s) found
=> usb reset
(Re)start USB...
USB: EHCI fail to reset
Error, couldn't init Lowlevel part
This patch fixes this problem. Now "usb reset" can be called multiple
times.
