[PATCH v2 1/7] usb: gadget: pch_udc: Replace cpu_to_le32() by lower_32_bits()

[Andy Shevchenko]

Either way ~0 will be in the correct byte order, hence
replace cpu_to_le32() by lower_32_bits(). 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")
