From: Sam Shih <sam.shih@xxxxxxxxxxxx> Add APMIXED, ETH, INFRACFG and TOPCKGEN clock drivers which are typical MediaTek designs. Also add driver for XFIPLL clock generating the 156.25MHz clock for the XFI SerDes. It needs an undocumented software workaround and has an unknown internal design.

v6: no changes v5: * more nicely format macro defintions * register reset controller for ethwarp clock controller * drop redundant GATE_SGMII1 which is indentical to GATE_SGMII0 in favor of single GATE_SGMII macro v4: * make use of existing GATE_MTK_FLAGS macro * reformat to max. 100 columns * cosmetics drivers/clk/mediatek/Kconfig | 9 + drivers/clk/mediatek/Makefile | 5 +
