1b Update PHY control mode (active load)
0: Load the new VControl value to PHY/common block
1: Only VControlModeSel value to PHY will be updated for selecting
different PHY status group (see PHY status registers, EOR_Reg x88 ~
x90). But VControl[6:0] value inside PHY won't get affected.
0h Select the corresponding port PHY or common block to load the
VControl bits.
