usb: ulpi: Fix compile warning in read/write on 64-bit machines.
ulpi_read and ulpi_write are used to read/write registers via ULPI bus. Code generates compilation warnings on 64-bit machines where pointer is cast to u32. This patch drops all but last 8 bits of register address. It is possible, because addresses on ULPI bus are 6- or 8-bit. It is not possible (according to ULPI 1.1 spec) to have more than 8-bit addressing. This patch should not cause regressions as all calls to ulpi_read/write use either structure pointer (@ address 0) or integer offsets cast to pointer - addresses requested are way below 8-bit range.
