Johan Hovold 19b9a83e21 USB: musb: omap2430: fix kernel panic on reboot
Cancel idle timer in musb_platform_exit.

The idle timer could trigger after clock had been disabled leading to
kernel panic when MUSB_DEVCTL is accessed in musb_do_idle on 2.6.37.

The fault below is no longer triggered on 2.6.38-rc4 (clock is disabled
later, and only if compiled as a module, and the offending memory access
has moved) but the timer should be cancelled nonetheless.

Rebooting... musb_hdrc musb_hdrc: remove, state 4
usb usb1: USB disconnect, address 1
musb_hdrc musb_hdrc: USB bus 1 deregistered
Unhandled fault: external abort on non-linefetch (0x1028) at 0xfa0ab060
