usb: musb: Modify the "HWVers" register address

commit 6658a62e1ddf726483cb2d8bf45ea3f9bd533074 upstream.

musb HWVers rgister address is not 0x69, if we operate the
wrong address 0x69, it will cause a kernel crash, because
there is no register corresponding to this address in the
additional control register of musb. In fact, HWVers has
been defined in musb_register.h, and the name is
"MUSB_HWVERS", so We need to use this macro instead of 0x69.
