[PATCH] echi: remove structure packing from ehci_def

[Rabin Vincent]

As pointed out by Arnd Bergmann, in include/linux/usb/ehci_def.h, struct
ehci_caps is defined with __attribute__((packed)) for no good reason,
and this triggers undefined behaviour when using ARM's readl() on
pointers to elements of this structure:
