[U-Boot] [PATCH] usb: musb-new: Add CONFIG_USB_MUSB_INIT_TIMEOUT

[Alex Kiernan]

Make the timeout in musb_lowlevel_init() configurable from the 1s default.
Some USB memory sticks take longer than 1s to connect and so whilst
usable in Linux aren't usable in U-Boot. The default in Kconfig is still
1000ms, so this should be a non-change for any existing users.
