Subject: [PATCH v1 1/6] usb: gadget: pch_udc: Drop unneeded cpu_to_le32() call

Either way ~0 will be in the correct byte order,
hence drop unneeded cpu_to_le32() call. Moreover,
it makes sparse happy, otherwise it complains:

pch_udc.c:1813:27: warning: incorrect type in assignment (different base types)
pch_udc.c:1813:27:    expected unsigned int [usertype] dataptr
pch_udc.c:1813:27:    got restricted __le32 [usertype]

Fixes: f646cf94520e ("USB device driver of Topcliff PCH")
