[U-Boot] [PATCH 3/3] clk: MediaTek: add hifsys entry for MT7623 SoC.

Mon Jul 29 14:17:48 UTC 2019
This adds high speed interface subsystem - hifsys (i.e. PCIe and USB)
for MT7623 SoC and enables its reset controller.
The control block is shared with ethsys and accordingly rename the
related defines.
