18 case 1: only supports xHCI driver;
19 case 2: supports dual-role mode, and the host is based on xHCI driver.

111 A phandle to syscon used to access the register of the USB wakeup glue
112 layer between xHCI and SPM, the field should always be 3 cells long.
116 The first cell represents a phandle to syscon
118 The second cell represents the register base address of the glue
121 The third cell represents the hardware version of the glue layer,
122 1 is used by mt8173 etc, 2 is used by mt2712 etc
