on Hotack HTC-T010-V2 board, kernel hangs just after below message,
> rockchip_clk_init_from_table: setting parent of aclk_peri_pre to cpll

ARM: dts: Add support for Hotack HTC-T010-V2 board

this patch adds support for Hotack HTC-T010-V2 board.

HTC-T010-V2 board is used in some RK3188 based "HDMI stick" products.
(e.g. MK802IV with AP6210 model, etc)

probably HTC-T010-V3 board will work too.

dwc2 is working without phy support. disable phy related configs.
