clk: spacemit: k3: fix USB2 bus clock

Browse Source 
According to SpacemiT K3's updated docs, the USB2 ahb reset and USB2 bus
clock enable bit was wrongly swapped, the correct one should be:

Register : APMU_USB_CLK_RES_CTRL
bit[1]   : usb2_port_bus_clk_en
bit[0]   : usb2_port_ahb_rstn

Fixes: e371a77255 ("clk: spacemit: k3: add the clock tree")
